Real voter fraud in the U.S. is almost nonexistent. Yet the GOP acts like it is a threat to democracy and national security. They have launched a national witch hunt to disenfranchise certain voters. The only threat to republicans security is that Obama may win a second term.
Pennsylvania is now the ninth state in the past year to enact a photo ID law. Like most of those other eight states, it was a republican-led state legislature and republican governor that made it happen in Harrisburg. These laws hurt the elderly, poor and minorities, many of whom call themselves democrats. Republicans know they can't win the 2012 election fairly so they resort to enacting racist unconstitutional laws to tip the vote their way.
