If you’re interested, I’m live-blogging the Michigan and Arizona primary results over at my place, updating frequently with loads of commentary and analysis.

I predicted a 3-point Romney win and it looks like he’ll take it, winning what was seen as a toss-up. And he’ll win Arizona by a wide margin — the networks have already called it.

So what now? Is the story that Romney withstood Santorum’s challenge and will now cruise to the nomination? Does this now take the air out of Super Tuesday? Or will Romney continue to fail to pull away? And what if he ends up doing poorly on Super Tuesday?

The cracks in the GOP are only getting deeper.
