Looking forward to popping into a bar after work to watch the election results roll in from across the country over a few pints of beer? You'd better not live in Louisville or Charleston -- or anywhere else in Kentucky or South Carolina. Because those are the last two states in the country to have laws banning the sale of alcohol on Election Day on the books.

Five other states -- Delaware, Idaho, Indiana, Utah and West Virginia -- had similar laws this time four years ago, but have since repealed them. All were artifacts of stricter Prohibition-era blue laws, many of which have been rolled back across the country in recent years. The Election Day laws in particular have been traced back to a desire to combat the 19th century tradition of corrupt political bosses trading votes for free booze -- a practice that seems almost quaint in the era of Citizens United.
