Many conservatives are finding it difficult to pick a presidential candidate. Each of the men running for the Republican nomination has strengths, and none has everything — all the traits, all the positions — we are looking for. Equally conservative analysts can reach, and have reached, different judgments in this matter. There are fine conservatives supporting each of these Republicans.NR cites the pull-apart factor for rejecting Huckabee and Rudy:
Our guiding principle has always been to select the most conservative viable candidate. In our judgment, that candidate is Mitt Romney, the former governor of Massachusetts. Unlike some other candidates in the race, Romney is a full-spectrum conservative: a supporter of free-market economics and limited government, moral causes such as the right to life and the preservation of marriage, and a foreign policy based on the national interest. While he has not talked much about the importance of resisting ethnic balkanization — none of the major candidates has — he supports enforcing the immigration laws and opposes amnesty. Those are important steps in the right direction.
Uniting the conservative coalition is not enough to win a presidential election, but it is a prerequisite for building on that coalition. Rudolph Giuliani did extraordinary work as mayor of New York and was inspirational on 9/11. But he and Mike Huckabee would pull apart the coalition from opposite ends: Giuliani alienating the social conservatives, and Huckabee the economic (and foreign-policy) conservatives. A Republican party that abandoned either limited government or moral standards would be much diminished in the service it could give the country.They laud McCain but bash McCain-Feingold and other missteps. They think Fred's conservative, but don't trust his ability to run a large enterprise.
