The pundits are all over the significance of today's news, which I think will be huge. I would just add one thought: Powell's calm, dignified recitation of McCain's faults and weaknesses as a presidential candidate, and his brushing off of the Bill Ayers nonsense and other extraneous matters, underscores just what a small and petty man McCain has become. I have little doubt that Americans are ready to embrace someone and something new.

Powell's finest moment: So says Juan Cole, in a very good post that blogger Richard reproduces in the Comments below, but which I would also like to flag here (you may have to scroll down to find this because Cole's blog does not have individual post links.) Among many other things, Cole makes clear that Powell did not endorse Obama just because he is Black, as some rightwing slimeballs--including Pat Buchanan on Chris Matthews' "Hardball" last night and Rush Limbaugh on his radio show--are trying to make us think (by the way, I don't hear anyone saying that Henry Kissinger and Alexander Haig endorsed John McCain because he is white, which makes such statements prima facie evidence of racism.)

How to deal with those robo-calls: Some advice from historian Andrew Hunt.

GOP Site Removes Call to Torture Obama. Read about it here.

Spread the wealth! As most of you know, McCain has been attacking Obama as a "socialist" these past days, based on a distortion of what Obama said to "Joe the Plumber." Yet another example of the McCain campaign's cluelessness: Spreading the wealth around might be sounding like a good idea to Americans struggling from the effects of an economic system designed to make the rich richer and the poor poorer.

"Joe the Plumber" should vote for Obama. That's the implication of Monday's Paul Krugman column in the Times, which points out that plumbers would pay less taxes under Obama's plan (and Krugman exposes the faux populism of the Republicans while he is at it.)

Promises, promises. By the way, how is McCain going to keep all the campaign promises he is making with an even stronger Democratic majority in both the House and Senate, no matter who wins the presidential election? Just wondering.
