WASHINGTON, D.C. – One of the most contentious battles in politics isn’t just the current battle for the White House, it’s also the upcoming battle over who could ultimately end up in the halls of Congress and state capitols everywhere, in a process called redistricting.“The basic idea underlying that system is that we should form a constituency with people who live near us,” said Charles Blahous, a senior research strategist at the Mercatus Center at George Mason University in Virginia.New district maps are created based on census population numbers every 10 years. Yet, those maps can end up getting distorted to favor one political party over another when gerrymandering comes in to play.“I think gerrymandering is of concern to most voters because it seems to violate the foundational principle of our representative system, which is that we are divided into districts geographically,” Blahous said.Geography is something gerrymandering throws out the window. Some of the unusual congressional district maps can end up looking like animals.There is Maryland’s Democratic 3rd district, which looks like a snake, stretching from Baltimore into counties south. There is also northern Ohio’s Republican 4th district, known as “the duck.”So, who designed these?“The Constitution gives the power to state legislatures to draw these maps,” Blahous said.Since politicians draw the maps, they can be skewed to favor a particular party or incumbent. However, they can also be used to favor people from a particular racial or ethnic group, who have often been under-represented in the halls of power, in order to comply with federal Voting Rights Act rules on representation.Still, there are now efforts to take the map drawing out of the hands of politicians.In Virginia, voters will decide this November whether an independent commission should be in charge of the process instead. There are other ideas emerging, too: like using artificial intelligence to make the maps.“It takes an enormous computer capacity, which was not there 30 years ago, and writing the programming to make that all happen is also not a trivial matter,” said political science professor Bruce Cain, director of the Bill Lane Center for the American West at Stanford University.Prof. Cain said he and a colleague, Prof. Wendy Tam Cho of the University of Illinois at Urbana-Champaign, believe an algorithm they’ve developed might be the best alternative for making fairer maps.“What you want to be able to do is take every plan and classify it and say, ‘yeah, this one's better for minorities, this one's better for compactness,’ but is there something that combines both of them?” he said.It is all part of the ongoing effort to make sure America’s representative democracy remains truly representative of the people. 2801

We have increasingly been hearing about security and privacy problems with smart devices that are connected to the internet. All of these devices, from doorbells to thermostats, could one day have what's almost like a nutrition label on them.The label would tell you about the security and privacy features of the device.Researchers from Carnegie Mellon University came up with the design for what the label could look like.The researchers want to have the label on the packaging and the website. They expect there would still be impulse buys where you would disregard the label, but it would help in other situations.“When they're making a more considered purchase for their home or if they're giving it as a gift to some else or if it's something that's more sensitive, I’m not just buying a light bulb, but I'm buying something that's health-related or something that has a video camera attached to it and I want to know where that video data is going, then I expect people will pay attention,” said Lorrie Cranor, Director of CyLab.Cranor, one of researchers who has been working on this, says the biggest obstacle right now is getting companies to buy in.She says to really have widespread adoption, there needs to be regulation that requires it. A number of pieces of regulation in Congress have mentioned the idea of a label, but none of them have advanced.She says having marketplaces require it would help as well.“You want your item to be sold in Best Buy or on Amazon or whatever, you have to have this label or we're going to feature the products that have this label,” said Cranor.This proposed label is for when you're buying a smart device, but there's already a recently created tool to find out about the smart cameras or location trackers you didn't buy that you may encounter around the city.The IoT Assistant app will notify you how your data is being collected by those devices. You can download it for free in the App Store or Google Play. 1969

WASHINGTON, D.C. – The U.S. Postal Service has launched a new website to help Americans vote by mail in the November general election.The USPS announced the creation of usps.com/votinginfo Friday, saying the site is meant to provide the electorate with clear and concise information about voting by mail.The website is also meant to help election officials as states choose to expand mail-in voting options for the upcoming elections, so that voters don’t have to risk contracting the coronavirus at the polls.For domestic voters, the website provides direct links to federal election resources as well as links to state-specific resources. For overseas and military voters, the new site provides additional information, including links to resources supporting their election participation.The site also highlights what the USPS views as the most critical information for voters who opt to vote through the U.S. mail: that, in requesting or casting a mail-in ballot, they not only must comply with their local jurisdictions’ requirements, but also should start the process early.To allow sufficient time for voters to receive, complete and return ballots via the mail, the USPS strongly recommends that voters request ballots at the earliest point allowable, but no later than 15 days prior to the election date.The Postal Service also recommends that voters mail their ballots at least one week prior to their states’ due dates to allow for timely receipt by election officials.Voters should contact their local election officials for further information about deadlines and other requirements.The USPS says it remains fully committed to fulfilling its role in the electoral process and can handle the anticipated increase in election mail.“Election officials and voters are being asked to be mindful of the Postal Service’s established delivery standards and consider how the mail actually works, so that voters have adequate time to request, receive, complete and send their mail-in ballots,” wrote the USPS in a press release. “The Postal Service will continue to do everything in its power to efficiently handle and deliver Election Mail, including ballots, in a manner consistent with the proven processes and procedures that have been relied upon for years.” 2273
