I like all of our candidates except Ron Paul and Brownback, but I like Brownback's tax proposals.
I like all of our candidates too, with the exceptions you noted, and, I think I'd add Huckabee to the exceptions list due to his amnesty position and his lackluster support of the President's surge. IMHO, though, only Rudy, Romney and McCain can win in the general -- and with McCain, I'm not so sure. Time will tell.
I haven't given my time or money to anyone yet. Waiting to see the debates.
