You think so. I think he's the easiest based on geography, personality, being a insider Washington guy, and temperment(not like Dean's, but has one). As for his war record, he also turned his back on the country while our guys were still there.
Clark's tough since he's unpredictable. Gep's gone, but he would have been tough. Dean still can be scary, although he may have beaten himself for being a jackass. Edwards I think would have been very tough....in 2008 or 2012.
