A Hillary v McCain matchup will actually help the congressional GOP IMO.
I am not a huge fan of McCain (I supported Fred Thompson), but I think the polarizing affect of Hillary, the fact that I think she will bring out the GOP vote (even overcoming McCain’s wishy washiness) AND drive some independents and maybe even a few white male moderate to conservative DEMS into McCain, which might translate into a few more votes down the ballot for the GOP.
I am no fan of Huckabee, Romney and not fired up about McCain, but if I would drive through a hellstorm to vote for Cartman, Adam Sandler or even my dog over Hillary Clinton.
I hope you still do, since he's still in the race. ;o) I'm looking forward to voting for him on Super Duper Tuesday!
