The first three nomination races have not gone well for former Vice President Joe Biden. The once frontrunner for the Democratic nomination has struggled to attract voters to the polls thus far. But Saturday’s primary in South Carolina could be what the doctor ordered for an ailing campaign. Or it could be what brings the campaign to a halt going into Super Tuesday. POLLS CLOSE AT 7 P.M. ET ON SATURDAY.South Carolina represents the most delegates (54) that have been up for grabs in a nominating race so far. It is also far more diverse than Iowa and New Hampshire. While Biden was hopeful a more diverse electorate would improve his fortunes in Nevada, he watched as Sen. Bernie Sanders won in convincing fashion last week. Still, Nevada was Biden’s best performance of the three races so far, but his second-place finish only showed how much ground he has lost to Sanders. DELEGATE COUNT THROUGH FEB. 28:SANDERS: 45BUTTIGIEG: 26BIDEN: 15WARREN: 8KLOBUCHAR: 71991 NEEDED TO WIN THE NOMINATIONPolling for Saturday’s primary indicates South Carolina could put Biden back into the mix as Democrats prepare for the most important night of the nomination on Tuesday. Monmouth University released a South Carolina primary poll on Thursday indicating Biden was leading the pack with 36%. The poll showed that Sanders and Tom Steyer were jockeying for second with 16% and 15% respectively. 15% is a key figure for the race as it is the threshold to receive delegates – anything less results in a goose egg. Helping Biden’s standing with the black vote was this week’s endorsement from Rep. Jim Clyburn. Clyburn, the third-most powerful Democrat in the House, has been one of South Carolina’s most recognizable Democrats for decades. “I know Joe Biden. I know his character, his heart, and his record. Joe Biden has stood for the hard-working people of South Carolina. We know Joe. But more importantly, he knows us,” Clyburn told voters this week. Following Saturday’s race is Super Tuesday when one-third of all delegates are up for grabs. The night could be intriguing for several reasons. One is the foray of Mike Bloomberg into the race. He sat out the first four nominating contests, and has spent a fortune of his own money to advertise in delegate-rich states such as Texas and California. Super Tuesday also could provide clarity on which candidate or candidates will take on Sanders deep into the nominating race. Finally, it could give an indication on whether Democrats need to prepare for a brokered convention. As Democrats allocate delegates proportionally, having a candidate such as Sanders come away with a majority of the delegates by July's convention could be a challenge. 2701

The Department of Housing and Urban Development is charging Facebook with violating the Fair Housing Act.HUD on Thursday said the social media giant is violating the federal act by "encouraging, enabling, and causing" housing discrimination through its advertising platform."Facebook is discriminating against people based upon who they are and where they live," HUD Secretary Ben Carson said in a statement. "Using a computer to limit a person's housing choices can be just as discriminatory as slamming a door in someone's face."Last August, HUD 560

The number of people worldwide who die from suicide is declining but one person still kills themselves every 40 seconds, according to new figures from the World Health Organization, which said countries needed to do more to stop these preventable deaths.Between 2010 and 2016, the global suicide rate decreased by 9.8%, the UN health body said in its second report on the issue. The only region to see an increase was the Americas."Every death is a tragedy for family, friends and colleagues. Yet suicides are preventable. We call on all countries to incorporate proven suicide prevention strategies into national health and education programs in a sustainable way," said WHO Director-General, Dr. Tedros Adhanom Ghebreyesus.WHO said close to 800,000 people die by suicide every year, more than those lost to malaria, breast cancer, or war and homicide, calling it a "serious global public health issue." It said only 38 countries had suicide prevention strategies.Suicide rates were higher than the global, age-standardized average -- 10.5 per 100,000 people -- in Africa, Europe and Southeast Asia.Worldwide, more men killed themselves than women, WHO said, with 7.5 suicide deaths per 100,000 women and 13.7 suicides per 100,000 men. The only countries where the suicide rate was estimated to be higher in women than men were Bangladesh, China, Lesotho, Morocco, and Myanmar."While 79% of the world's suicides occurred in low- and middle-income countries, high-income countries had the highest rate, at 11.5 per 100,000" people, WHO said."Nearly three times as many men as women die by suicide in high-income countries, in contrast to low- and middle-income countries, where the rate is more equal," the WHO statement said."Suicide was the second-leading cause of death among young people aged 15-29 years, after road injury. Among teens aged 15-19 years, suicide was the second-leading cause of death among girls (after maternal conditions) and the third-leading cause of death in boys, after road injury and interpersonal violence."WHO said one way to bring down the global suicide rate would be to limit access to pesticides, which -- along with hanging and firearms -- are the most common method of suicide. For example, in Sri Lanka, a series of bans on highly hazardous pesticides led to a 70% decrease in suicides, saving an estimated 93,000 lives from 1995 and 2015. Similarly, in South Korea, a ban on the herbicide paraquat was followed by a 50% decrease in suicide deaths from pesticide poisoning from 2011-2013.Other steps the WHO said have helped reduce suicides include educating the media on how to report responsibly on suicide, identifying people at risk early and helping young people build skills that help them cope with life stresses.World suicide prevention day is September 10. 2815
