In 2000, McCain took the left of the GOP, about 15%.
Bush took the base of the GOP + center, about 75%.
Keyes took the right 5%.
Pat took 5% with him to the Reform Party.
The problem with Keyes is that he attacks the base and the center with his holier than thou attitude. Now how the heck are you gonna win by doing that?
The GOP always picks the team player. Why do you think Bob Dole got the nomination in 1996? He took the left and center, about 55%. He was a team player. The base and right stayed home and he lost.
You have effectively delineated the problem. Where's ol' Bob now, other than in erectile dysfuntion commercials? I know, Pat did him in.
