Honestly, I don’t think it matters. I think Mitt is a bit more predictable. The main thing about Gingrich that worries me is that his philosophy doesn’t make sense, so I can’t predict his position on anything. I don’t believe he believes what he says. He’s a kind of pragmatist who is purely political. He is a tactician, and so anything he says, I don’t really believe. I don’t know what he really thinks.
Mitt is very similar to that. He has changed and moved right for similar reasons. Mitt seems more reasonable and Newt is a rabid politician (I don’t even know if he’s really right wing). But they both change depending on the wind. Which means I have no idea how they would be as President.
I guess either one would be equally bad compared to Obama. I don’t see any advantage to Obama in having one or the other as an opponent. Newt is a better attack dog, but I don’t know if that will really help him in the general election.
So, yes. Newt’s win is good or bad for Obama.
