I thought that in 2008 until McCain picked Palin and I saw (as in I knew personally) die-in-the-wool conservatives actually announce they were supporting Obama this time.
McCains VP choice was simply misunderstood. The role of the vice president is to be a spare. McCains young but clueless choice made sense if the VP was viewed as spare parts.
Romney comes across as a moderately competent political moderate
From his venture-capital experience he's had practice at seeking out what profits him while avoiding risk. So when he knows that revealing his tax returns or saying more about owning 9% of a Chinese electronics appliance manufacturer that many U.S. companies outsource to, he knows to clam up. (That is also a lesson some learned from Richard Nixon, whose approval rating went down every time he spoke publicly). McCain had full access to Romney tax returns and went with Palin instead. That says something. Romney also heavily panders or at least pays momentary lip service to whatever group he's targeting at a particular moment. It's not moderate to be unwilling to publicly support any restrictions on assault weapons, it's pandering. He comments and actions later often don't agree. Ask any log-cabin Republican about that.
Saying whatever profits or otherwise suits him, he cannot be trusted.
His non-scripted comments in the EU down he's not very good on his feet. Unless you're impressed with him not even remembering a British officials name and calling him Mr. Leader. While he promised transparency and press access including to fund raisers on the way, but he denied them access in Israel. Policy comments made relating to Iran were reckless. Describing the differences in quality of life between Israelis and Palestinians as "cultural advantages" with no mention of settlements or occupation could best be viewed as Palinism.
He only answered three questions for the press traveling with him, and a Romney representative actually said "Kiss my ass" and "shove it" to the press while in Poland.

And, in catering to older confused Republicans that think the cold war is still going, he names Russia as number 1 geopolitical foe. This as Russia grants NATO supply routes to Afghanistan. (A bunch of supply trucks coming from Pakistan were blown up recently).
I wonder what he thinks of the Swedish Teddy Bear invasion.
