If more of Iowa's independent voters participate in the Democratic primary tonight, it could be a warning to Republicans. The support of independent voters, which made possible the 2006 Democratic takeover of Congress, may put a Democrat in the White House.
The latest poll by the Des Moines Register indicates that one-third of independent voters will vote Republican, while two-thirds will vote Democrat. Also, if poll predictions prove correct, overall turnout at the Democratic caucus could double the Republican turnout.
As the primary season takes off, we may see indications that crucial swing voters identify with core Democratic ideas — such as ending the war in Iraq and providing greater government support for the middle class.
