My friends on the right are cheering the rather dull speech given last night at the Republican National Convention by U.S. Sen. Joe Lieberman (I-Warsville). Lieberman used to be a Democrat, but he [hearts] the ongoing conflict in Iraq and John McCain’s support for it, so he decided to switch sides and root for Republicans this year.

That’s fine, but there ain’t no coming back.

That’s not to say that you can’t, as a partisan, disagree with things that happen on your side of the aisle. But saying that Jill Long Thompson’s campaign ads are terrible or that City-County Council Democrats have an image problem is not the same as endorsing Mitch Daniels or running as a Republican.

Lieberman made his bed; now he gets to lie in it. Maybe his decision to play on the GOP team will inspire some in the middle, but I’d argue the issue that he’s championing — George W. Bush’s endless war — isn’t a terribly popular one.

Whatever happens, he’s either going to be a Republican or stuck somewhere in the middle. I don’t think there are too many Democrats who’d accept him back with open arms after he cheated on them and bragged about it on national television.
