WASHINGTON, D.C. -- Milwaukee, Charlotte, Jacksonville: all cities that, at one time or another, prepared to host one of this year’s two major political conventions, along with tens of thousands of people.The coronavirus, though, put all of that on ice.“We were going to show the world all the great things Milwaukee has to offer, so it’s disappointing this had to happen to us this year,” said Wisconsin resident Katie Dahm.Professor Barry Burden heads up the Election Research Center and is a political science professor at the University of Wisconsin in Madison.“The role of the convention will definitely be different this year,” he said. “Research shows that conventions have had smaller and smaller impacts over the years.”Both the Democratic and Republican conventions are now, for all intents and purposes, virtual. So, what might that look like?“They will be highly-produced, slick productions that have been prepared in advance,” Prof. Burden said. “So, they have removed some of the uncertainties and spontaneity that happens at a convention. That may remove some of the excitement.”George Washington University media and public affairs professor Peter Loge agrees with that – up to a point.“There won't be the spontaneity,” Loge said, but also added, “I think the nets will still have to cover it because it's such a different convention, right? What's actually going to happen? What are we going to do? It's new. It's new and a different thing.”Loge also said the novelty of a virtual convention – unheard of until now – may drive people to check it out, either on TV or online.“We all want to feel a part of a special moment for what we think is an important moment in American history,” he said. “And I think people will tune in for that.”Offering an opportunity to potentially capture the attention of those who may not usually watch a big party thrown by political parties. 1898

WASHINGTON, D.C. – One hundred years after the 19th Amendment became law, eligible women voters could end up as the definitive political power in the 2020 election.“Women are the most consistent, reliable voting bloc across the country, across the elections, year in and year out,” said Jeanette Senecal with the League of Women Voters.The numbers bear that out. According to the Pew Research Center, women have outnumbered men in the voting booth in every presidential election since 1984.In 2016, 63% of eligible women voted, versus 59% of men.Those numbers have implications for both the Democratic and Republican parties, according to American University professor Jane Hall.“We are seeing a very striking acceleration of what has been a trend for some time, which is a gender gap between women voting for Democrats and men voting more for the Republican party,” Hall said.In the 2018 midterm elections, that gender gap became pronounced.Among registered voters, 50% of men identified as either Republican or leaning Republican, while 42% of men went with Democrats, a difference of 8%.Yet, among women, that gap more than doubled: 56% of women identified as Democrats, but only 38% with Republicans – a gap of 18%.How women choose to vote, though, is more complex than just two political parties, said Howard University political science professor Dr. Keesha Middlemass. There are differences in race and ethnicity, as well as levels of education and income.“We have to think about women as multiple blocs of voters,” Dr. Middlemass said. “They’re not a monolith.”That’s something the two presidential candidates seem to realize. President Donald Trump recently said he’s trying to appeal to what he calls “suburban housewives,” while Joe Biden picked a woman, California Senator Kamala Harris, as his running mate.“Anecdotally, talking to a lot of women: representation matters, seeing yourself there matters,” Hall said.What impact all of this has on the upcoming election remains to be seen.“Women want policies: ‘how are you going to make my life better?’ well, that requires policy,” Dr. Middlemass said. “But that whole idea of gender politics is going to be very evident in getting out the vote.”All of it is happening in an election where gender could tip the balance of power one way, or another. 2318

WATCH ABC's 20/20 on ABC 10 at 10 p.m. Friday.Rebecca Zahau, girlfriend of pharmaceutical tycoon Jonah Shacknai, was found dead – hanging from the balcony of his Coronado home, completely nude, with her bare feet bound, hands tied behind her back and shirt stuffed in her mouth.Only two days before, Jonah’s six-year-old son, Max, had somehow fallen over a staircase banister in the same home and later died.Given the circumstances of her death, Rebecca’s family remains skeptical of the police ruling that her death was a suicide and alleges that Adam Shacknai, Jonah’s brother and the only other one staying at the property the night Rebecca died, is to blame and filed a wrongful death lawsuit against Adam.ABC News Senior Legal Correspondent Sunny Hostin reports on the story’s twists and turns. And in the midst of Rebecca’s family’s suit that went to trial this week, “20/20” features an exclusive first interview with Jonah about Rebecca and Max’s deaths. “20/20” airs on Friday, March 2 at 10 p.m. on ABC10. 1038

WASHINGTON, D.C. – It will be even longer until Americans can travel aboard cruise ships. A group of the nation’s top cruise lines have agreed to suspend their U.S. operations even further.Cruise Lines International Association (CLIA) announced Wednesday that its ocean-going cruise line members will suspend their U.S. operations until at least Oct. 31, 2020.The association, made up of companies like Carnival and Norwegian cruise lines, had previously suspended U.S. operations until Sept. 15. The CDC’s no-sail order lasts through Sept. 30.The association said it was a hard decision to further suspend operations, but it must be done to protect the public from the devastating effects of COVID-19.“This is a difficult decision as we recognize the crushing impact that this pandemic has had on our community and every other industry,” said CLIA in a statement. “However, we believe this proactive action further demonstrates the cruise industry’s commitment to public health and willingness to voluntarily suspend operations in the interest of public health and safety, as has occurred twice prior.”CLIA says its cruise line members will continue to monitor the situation with the understanding that they will revisit a possible further extension on or before 30 September 2020.“At the same time, should conditions in the U.S. change and it becomes possible to consider short, modified sailings, we would consider an earlier restart,” wrote CLIA.CLIA says its most recent economic impact study indicated the U.S. supports nearly half a million American jobs and generates billion annually in economic activity throughout the country. According to the association, each day of the suspension of U.S. cruise operations results in a loss of up to 0 million in economic activity and 800 direct and indirect American jobs.The impact of the suspension is particularly profound in states that depend heavily on cruise tourism, including Florida, Texas, Alaska, Washington, New York and California, according to CLIA.The following global cruise lines are part of the association:AIDA CruisesAmerican Cruise LinesAzamaraCarnival Cruise LineCelebrity CruisesCelestyal CruisesCosta CruisesCrystal CruisesCunard LineDisney Cruise LineHolland America LineMSC CruisesMystic CruisesNorwegian Cruise LineOceania CruisesPearl Seas CruisesPONANT Yacht Cruises and ExpeditionsPrincess CruisesRegent Seven Seas CruisesRoyal Caribbean InternationalScenic Luxury Cruises and ToursSeabournSeaDream Yacht ClubSilversea CruisesTUI CruisesVirgin VoyagesWindstar Cruises 2562

WASHINGTON, D.C. – If Joe Biden wins the presidency, the former vice president says he would rejoin the Paris Agreement on his first day in office.The United States formally withdrew from the agreement on Wednesday, as President Donald Trump promised to do last year.“Today, the Trump Administration officially left the Paris Climate Agreement. And in exactly 77 days, a Biden Administration will rejoin it,” Biden tweeted Wednesday in reaction to Trump’s actions.The agreement is a global pact that was put together by the United Nations in 2015 to help avert the threat of catastrophic climate change.The central aim is to strengthen the global response to the threat of climate change by keeping a global temperature rise this century well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit the temperature increase even further to 1.5 degrees Celsius.Scientists say that any temperature rise over could have devastating impacts on parts of the planets, including rising sea levels, an increase in tropical storms and worsening droughts and floods.A total of 189 countries remain committed to the accord, according to The Associated Press. 1182
