When comedian Al Franken joined the U.S. Senate this year, the idea of it being a highly select and serious chamber loosened up considerably. So why not Sen. Lou Dobbs? The ousted CNN host (in photo) is being discussed as a potential challenger to Sen. Robert Menendez, D-N.J. But in a Monday interview, the self-described "Mr. Independent" said he also is thinking about a White House run. "I think that being in the public arena means you've got to be part of the solution." No word on whether Dobbs would run as an independent or a Republican.
