Anyone who can look at this crop of Democrats and contemplate wasting their vote by staying home or voting for a determined also-ran is a hideous traitor to the conservative cause.
How about those that would vote for a back-stabbing RINO?
RINOs are better than Democrats...in McCain's case because he's pro-military and pro-life; in Giuliani's case because he's pro-Israel, pro-tax cuts and pro-War On Terror; in Huckabee's case because he's pro-life, and in Romney's case, because he's converted to a pro-life stance and is pro-business. Of course, my choice Fred Thompson isn't a RINO at all and he's the pick of this crop.
There's always a reason to vote for the person with the most conservative positions on the most issues who is capable of winning...that would be either the Republican or the Democrat when it comes to presidential primaries and general elections.
