It highlights the main problem McCain had as well. Romney the governor != Romney the nominee.
I could get behind Romney the governor, an even keeled leader willing to fix things. Mostly moderate with a strong pro-business, low regulation slant but with little or no pandering to the evangelical vote. Essentially the kind of Republican the Tea Party morons want to run out of the party. So come primary he flips every, or nearly every, moderate view he had to the accepted far right, evangelical view to grab their vote and get the nomination. When he went to pick his VP he doubled down on Tea Party rhetoric rather than moderate views with an eye towards bipartisanship.
I'd like to see change from Obama and Romney the governor might have been that person but Romney the nominee just isn't. I can't trust what he says he believes, without details to his plans I can't trust that those details won't contain items that I find completely distasteful. I can't look at his record as governor as he has clearly changed his mind on how a leader should act. He lost his identity in his race to pander to the far right and shows no signs of reversing that course.
This is what the article is referring to. Romney's shift may have gotten him the nomination but it all seems pretty hollow when he's just saying what the right folks want to hear.
