If all you've got to hang your hat on is the abortion issue, it's a very weak foundation. Mitt's views on abortion is actually more conservative than about 80% of the rest of the country and more conservative than the current occupant of the White House to boot. It's simply not going to be a factor in this next election cycle.
Personally, I think at this point in time, Mitt Romney give the GOP the best chance to hold the White House in 2008. Somebody better might come along but they better come along pretty quick because time is running out.
Abortion, second amendment, gay agenda, loss of business and population.
Much more than one.
Ah yes, 40 years of steadfast support for legal abortion and Roe v Wade. No big deal.
And of course you completely ignore Mitt's other campaign planks:
Liberal gay activists as judges!
Assault weapons ban!
Gay rights!
Force all hospitals to dispense abortion drugs!
Embryonic stem cell research!
I get very suspicious of politicians who's "culture of life" positions (abortion, civil unions, gay marriage, other gay issues) "evolve" depending on the audience as Romney's do.
I also beg to differ with you that my complaint is one issue (abortion). I can add his immoral support of embryonic stem cell research, forcing Catholic hospitals to violate beliefs by forcing them to provide "reproductive health" services including contraception, his support to the gay agenda (and I don't mean just civil unions). Romney has compiled a mostly pro-gay record as governor. "Romney has appointed several openly gay people to key positions, endorsed openly gay legislative candidates, and declined to gut the Governor's Commission on Gay and Lesbian Youth" to quote the American Family Association
To me he seems like Bill Clinton in the sense that he talks out of both sides of his mouth to deceive and gain votes. He lacks core convictions.
I put him in the McCain/Guiliani category. Certainly better than anyone the Demoncrats will put up, but nowhere near a candidate I would be enthusiastic about.
