If you think the U.S. Senate is polarized now, just wait.
Indiana State Treasurer Richard Mourdock, the man who trounced six-term Sen. Richard Lugar in Tuesday's Republican primary for not being conservative enough, has served notice that if he is elected in November things will get even worse.
Mourdock, who had strong backing from the Tea Party and other ultra-conservatives, told Fox News and others that he wants more partisanship, not less, and he believes bipartisanship means Democrats must accept GOP positions.
