Wisconsin isn't the only state voting today

While the nation's attention may be focused on voting in the Badger State today, Wisconsin's voters aren't the only ones heading to the polls today. Five other states are holding their various presidential and congressional primaries today as well:

California will hold its first official "free-for-all" primaries today -- where the top two vote-getters advance to compete in the general election, regardless of political party affiliation.

New Jersey is a battle of the Democratic titans today as Obama-backed Steve Rothman faces the Bill Clinton-backed Bill Pascrell in their primary race.

In addition, New Mexico voters will decide on their pick in a senate Democratic primary, and Montana and South Dakota also hold their primaries today.
