Here’s why it’s hard to work up much enthusiasm for Rick Santorum. He’d be another George Bush.

From a small-government perspective, we’re doomed to have a dud in the White House regardless of the outcome (barring a brokered convention). So it’s important to try to get as many true classical liberals into the Congress as possible to check the nanny compulsions emanating from the White House.

Santorum doesn’t think much of the Second Amendment, either.

…is faltering in Iowa:

Bobby Burns has had a dramatic change of heart.

Burns, 23, was one of those young people swept up in Barack Obama’s 2008 presidential campaign. Three years and one college degree later, he cannot imagine a scenario in which he would consider voting for the president’s re-election.

“I guess you could say I have seen the light,” he said.

On Tuesday he will caucus in a precinct right down the road from where he grew up. His vote will go for Mitt Romney.

It’s not just Iowa. And this is the president’s problem. There are a lot of people who feel this way. On the other hand, I think you’d be pretty hard put to find anyone who voted for McCain who’s going to vote for him in November.
