The country club wing of the GOP and some conservative media outlets are promoting a Hobson's choice of three non-conservative candidates. It is 17 months to the 2008 Republican National Convention, and 20 months to the general election. The Republican Party and America should strive for someone better than Rudy McRomney.
In the last election (the one we lost) the Dems let go of their litmus test, and pro-life and fairly conservative candidates took over quite a few Republican seats.
Casey couldn't speak at the convention because he refused to endorse Clinton. Lieberman's problem was that he lost the Democratic primary.
