Sorry, but I don't believe Abortion views are the only test to whether one is a "Conservative" or a Liberal. And frankly, having Libertarian Conservative leanings myself, I can understand his point.
I've written it before and I'll write it again.
If either McCain or Guliani is the Republican nominee, as many Conservatives as sit home, they still get elected.
If neither is the nominee because the true believers keep them from the nomination, as things stand today, and I don't expect them to get any better for Republicans, a Democrat is the next President.
It's a mistake to judge the rest of the party based on your own political leanings. What is apparently a non-issue to you is actually the prime mover for many active voters.
The political reality is that no social liberal has a chance to either win the GOP nomination in 2008, or can knock of the Democrat.
Have we forgotten the cause of Bush's wins in 2004?
When surveyed, 22 percent of voters in 2004 said "moral values" was the primary issue to drive them to the polls, even more than the economy and the Iraq war. A whopping 79 percent of such voters went for Bush. Without a certain social issue, marriage, Bush might not have won. He benefited greatly from the marriage amendments on ballots in twelve states.
It is foolish to believe the party can survive or win without that support. The party is becoming more conservative. Just ask Jim Jeffords.
