Primary day for Rep. Ron Paul

In five states across the nation, voters are heading to the polls today in primary races. We've got incumbents fighting to stay in office. Plenty of mud-slinging and some major cash being dropped. One of the big issues cropping up in a lot of these races: The controversy over a mosque and Islamic center in lower Manhattan. Rep. Ron Paul explains his take on the proposed mosque near ground zero, as well as Tea Party politics on CNN's American Morning Tuesday.
