Dave Weigel writes about "liberal bloggers" eager to back Bob Barr as an anti-McCain spoiler. You can sign me up. There's a certain number of people who aren't going to be on board for John McCain's vision of authoritarianism (in support of endless war) at home, and endless war (in support of authoritarianism) abroad but who also just aren't going to be very sympathetic to Barack Obama. If push comes to shove, I think Obama can get most of those people to vote for him. But I'd rather push didn't come to shove -- give traditionalist, small-government, small-r republican conservatives their Bob Barr to vote for and the Obama will win and the GOP might shift in a more product direction over the medium term.
