An Excellent Question

Doug Mataconis asks, "Are Republican voters suicidal?" That's in response to some strange numbers from inside that recent Michigan GOP poll:

As I noted in my earlier post, the latest poll from the Detroit News shows Rick Santorum leading Mitt Romney by four points among likely Michigan primary voters, this depite the fact that Romney clearly beats Santorum in the areas that one would think actually matter to voters:

Romney was four points behind with Santorum even though far more voters believe he’s a better leader than Santorum (38 percent to 15.8 percent) and more likely to beat President Barack Obama (42.2 percent to 18.4 percent).

It seems even Santorum voters don't think much of Santorum. If correct, it strengthens the argument that Santorum isn't much more than the most recent Not-Romney.
