Mayor Nutter - who has emerged as one of Clinton's chief surrogates over the last six weeks - is going to the wall for his candidate today. He's pressing the flesh with voters all over town, and it will be hard to avoid the mayor if you turn on the t.v. or radio today: CBS, MSNBC, NBC, Bloomberg, NPR and so on. It's no mystery why the Clinton campaign has put Nutter in such a high profile position: he's a youngish, reform-minded, African American mayor who is hugely popular in a city where Obama needs to do well to have a chance of winning the state. Of course Nutter gets something out of it to - a much larger national profile - as the Inquirer's Marcia Gelbart wrote earlier this month.
