After six posts on this subject, I’m plum out of things to say. Well, almost.

Surprising many Republican insiders, Mitt Romney is at the top of the vice-presidential prospect list for Sen. John McCain (R-Ariz.). But lack of personal chemistry could derail the pick…

Campaign insiders say McCain plans to name his running mate very shortly after Sen. Barack Obama (D-Ill.) does, as part of what one campaign planner called a “bounce-mitigation strategy.”…

One of the chief reasons the Massachusetts governor is looking so attractive is his ability to raise huge amounts of money quickly through his former business partners and from fellow members of The Church of Jesus Christ of Latter-day Saints, the Mormons.

McCain sources tell Politico that they believe Romney could raise $50 million in 60 days. One close Romney adviser said it could even be $60 million…

But there’s one big problem: Despite the buddy-picture choreography of a McCain-Romney campaign swing, McCain remains far short of enamored of Romney.

Supposedly Rob Portman and John Thune are the leading alternatives, although I don’t see how naming Portman would produce any “bounce-mitigation” from Obama’s VP pick since most conservatives couldn’t pick him out of a lineup. (As for Jindal, “insiders” evidently think his youth would backfire by making McCain look older by comparison, a point I’ve made before here.) Hugh Hewitt makes a good point too in arguing that if you want Mitt out there raising money — most or all of which would presumably go to the RNC, since McCain’s going to take public financing — then it makes no sense to wait until Obama makes his own VP pick. Tap Romney now and let him hit the trail as the newly crowned heir apparent. The fact that McCain wants to wait makes me wonder if I wasn’t right in this post in thinking that the two candidates are waiting to see if either will put a woman on the ticket to make a play for Hillary supporters. If Obama names Sebelius, McCain may feel he has no choice but to name Palin and break the “old white guy” monopoly on the GOP.

The only really surprising thing about this is that it’s now two months after Bob Novak first reported that Romney was the top choice, and he’s still the top choice — even after the strain on McCain’s relationship with evangelicals from his repudiation of Hagee and Parsley in May and the renewed outreach to social cons that began last week. Needless to say, for reasons legitimate and not so legitimate, Mitt isn’t necessarily the guy to get pro-life Christians fired up to turn out in the fall.
