Even as President Barack Obama was about to give his victory speech early Wednesday, dozens of Florida voters waited in line waiting to cast ballots more than five hours after the polls officially closed. Thousands of people in Virginia, Tennessee and elsewhere also had to vote in overtime. Well into the 21st century, it strikes many people as indefensible that the U.S. can’t come up with a more streamlined and less chaotic election system. The president said as much at the very start of his speech. “I want to thank every American who participated in this election, whether you voted for the very first time or waited in line for a very long time,” Obama said. “By the way, we have to fix that.” Easier said than done. There’s no single entity that sets the rules for voting in this country. Congress and the states enact overall election laws, but in most places it comes down to county or even city officials to actually run them. And those local systems are prone to problems. “We have 10,000 different systems. I wish there were only 50,” said Richard Hasen, a professor of law and political science at the University of California-Irvine and author of “The Voting Wars.”
