Conservatives worry (with good cause) that this fluke of Republican history might permanently deflect the course of the party away from conservatism. And indeed, we came to power in the party through, in part, a fluke of history. In the nomination fight of 1964 (in which I was a youth coordinator for Barry Goldwater in California)

Consider the recently very popular, tall, attractive, smart, eloquent, conservative, successful two-term Republican governor of one of our most populous swing states -- married to a beautiful Hispanic woman, no less. In fact, he is the son of a former president. Unfortunately for him and the party, he is also the brother of the current president.

Or consider the cheerful, handsome, solidly conservative Virginia senator expected to run as the son of Reagan. Unfortunately, he uttered three little syllables: Ma-ca-ca. He lost his re-election, and so adieu, Sen. George Allen.

The unfortunate part is that win or lose if McCain gets the nomination his people will take over the machinery of the national Republican Party. People who want to "think Mexico first". So they can really screw up the whole national party and make sure the Republicans are a minority for a generation.

McCain's 'wheels' came off his bus, maybe after he lost
the 2000 election. He had considered changing to the
Democrat party, even though he adamantly denies it, now.
He's too bitter and volatile, which should automatically disqualify him from holding the Office of President.
He's still making those back-room deals, even after
the amnesty disaster last summer. And he still giving his party members the finger! He's not to be trusted!
