I would have to exclude the present President, but certainly Reagan, GHWBush, Ford, to name a few. Most likely Nixon as well.
One thing for sure, even Reagan signed into law a more liberal abortion law when he was Governor of California.
Nobody who has opposed Second Amendment rights has ever won the Republican nomination.
So WE must ask ourselves is THIS the direction in which we want the GOP to go?
Rudy is the best chance to capture more of the Democrat voter, if that's to whom you wish to appeal.
Have you ever heard of single issue voters? I can think of two off the top of my head. One only votes to protect the unborn. The other only votes because they don't want to become criminalized by unconstitutional legislation, e.g. concerns supposedly protected by the Second Amendment. The left avoided those issues in the last election, Nov. 2006. They won the Congress when many of those voters stayed home.
You can criticize their voting habits as much as you please, but when both parties are contending for the muddy center, while the culture is being yanked to the left by the MSM, what do those folks have to vote for or against? Those voters aren't stupid. Pubbies don't raise taxes. Big deal, they raise fees, fines, surcharges, etc. That's what you get with invertebrate RINOs.
