"The base of the GOP simply will not support an openly liberal candidate on social issues.
Do not rule out some possible new names to surface in the coming months--it's early, so let's not carve each other up too much..."
You'd better hope things get cookin' real soon.
I along with many other conservatives will not support a candidate who cannot defeat Hillary just because they are MORE conservative.
And therein lies the problem that the Republican party will have to face.
On one side you have the "conservative base" who you say will never support a "liberal" like Giuliani(even though he isn't one), and the other side who will not support a candidate who can't defeat Shillary just to placate the conservative base.
But most of the base IMHO is looking for a positive, genuine conservative who will give America a clear choice--not just a different flavor of Democrat...
