Sirota makes a compelling case that Obama needs to pick a running mate that would help serve as a Populist contrast to McCain. With Jim Webb seemingly out of the running, my first choice is Sherrod Brown. However, because he is a highly unlikely pick, my first two realistic choices are Sebelius and Biden.
I know Biden is not exactly a raging Populist, but anyone that gets a 100% from the AFL-CIO has to have some Populist in him.
