Very good Yglesias column on TAP, like back in the old days:

Instead, Obama offered "the politics of fear." And, worse, we got a continuation of front-runner Hillary Clinton's politics of militarism. Throughout the campaign, there's been little consideration of the lessons future politicians will take if they see that having backed a Republican president in launching a war of choice that proved the most catastrophic foreign-policy mistake of the past 25 years didn't even cost Clinton the Democratic Party's nomination. Are the next crop of senators and representatives asked to endorse a preventive war on flimsy evidence going to think twice, or are they going to do what John Kerry and John Edwards did in 2002 and listen to political consultants who remind them that blind support for military adventures is crucial to one's presidential ambitions?

You know what would be even better than this column? A book-length version of this and similar arguments!
