Romney, it bears repeating, has an utterly conventional and mainstream take on economics. This isn't Keynes versus Hayek (or Minsky or Marx or etc.), here. It's Keynesian with one set of tuned parameters versus Keynesian with some slightly differently tuned parameters.
Romney would support having marginally more money in angel investors' pockets and making marginally less government-directed investments, e.g. Solyndra. So there's a minor Hayek vs. Keynes theme in the election.
Romney would also be pushing more stimulus via deficit-funded tax cuts, thereby increasing aggregate demand. So you could just as well say that Romney is the Keynes-side in this election, especially since the politics would be much more favorable toward Romney pushing stimulus than Obama.
In practice, you've got to look at what model of the world is motivating candidates and their economic advisers. In both cases, Keynes is whom they turn to.
His running mate was a self-identified libertarian... until he became the running mate, that is, and started fighting to be the one to pump the most money into Medicare.
