As we say in the South, "That's something nobody's ever gonna know". The GOP absolutely refuses to allow another conservative to run for president under their banner ever again. Wobbly and Dole couldn't do it, neither could Tio Jorge though he did squeak by a winner. 'Course none of those boys are conservatives.
Nope, and the reason as you know is massive 3rd world immigration since that time. I have to believe Bush understands well the political implications of uncontrolled immigration better than just about anyone. His actions indicate that he doesn't care if this hurts conservative republicans. The plan I think is to take the party further left and threaten conservatives all the way with the alternative of heavy socialism under the democrats.
