Here's my prediction (i.e. wild-guess) list:
1) Pawlenty – I’m afraid McCain will pick him because of the hoopla factor of having a favorite son selected at the MN convention. A really dumb and bad reason to select a running mate; but just what you might expect from a candidate who has spent the last 10 years as a Media darling and may embrace the distorted Washington News Media view of reality. A lot of NR-type Conservatives won’t like Pawlenty, because of some economics transgressions, but I hear that he’s a solid pro-life Governor and the pro-life evangelicals are probably the most volatile (i.e. disposed to sit it out) faction in the party, so it’s a decent choice.
2) Tom Ridge. They say that McCain is at his best when the chips are down, and that he tends to stumble when things are going well. In the past few weeks Obama’s European glamour tour and inept performance in the Saddlesore Church Forum, coupled with McCain’s embrace of Conservative themes has given McCain the momentum in this campaign. In other words things are going well, which is why I’m afraid McCain may pick Ridge, a pro-abortion Catholic, thus taking the wind out of the pro-life GOP base. Could McCain be so myopic when it comes to the enthusiasm and energy of the Party Base, and the willingness of pro-lifers to close their wallets, hang up their walking shoes, take a pass on voting? Answer: Gang of Fourteen. McCain may have a spotless pro-life voting record, but he doesn’t share the passion of the movement (so says Rick Santorum), so he doesn’t grasp the emotional effect of undermining the cause.
3) Romney – has faithfully campaigned for McCain since conceding the nomination. Romney would do excellent service as VP, and of course that would position him as the 2012 front-runner for the GOP Presidential nomination. Romney is my favored choice, and would be pleasing to both NR-type Conservatives and most Pro-Life Republicans. No need to please the "Pragmatists," since they've already got the top of the ticket. Romney handles himself well from the stump and in debate, and the main complaint against him as a Presidential candidate -- his supposed willingness to change his position on any issue in order to win -- is a virtue in a Vice President.
4) Lieberman – the end of the Republican Party. A good rule of thumb is that when all your enemies are enthusiastically telling you it’s a great idea, what they mean is that it’s a great idea FOR THEM. The GOP in the Senate, on the other hand, should be ready with some committee plums and NRSC $’s if the Dems are bitter and foolish enough to punish Lieberman for endorsing McCain and speaking at the GOP Convention. We could accept WFB’s chosen Senate candidate (you will, of course, recall that Lieberman first came to the Senate with the support of WFB and other NR-type Republicans, ousting that festering pimple of a Liberal Republican, Lowell Weicker, from the U.S. Senate back in the 1980’s) into our Big Tent.
5) David Petraeus – tough transition from no political experience to high-end politics, but it has been done before. A great man, a brilliant man and a great general. America probably needs him more at CentCom than gaveling the U.S. Senate. Better to save Petraeus as the Ike-like Presidential Candidate circa 2016.
6) Lindsay Graham – God forbid. Lindsay Graham was a good U.S. Representative, but now he is simply proof of the validity of The Peter Principle.
7) Sarah Palin – good novelty pick, and it would mean that McCain was changing his stupid position against drilling in ANWR.
