Edwards ENTIRE PLATFORM was based off his little "Two America's" thing. That was his entire focal point to his messages.
A comparable way for this is to have McCain spitting on a military guy, or purposefully skipping out on a visit to veterans, or found speaking disparagingly of the military, etc...because it'd show hypocracy a lot of his campaign is based around his military service.
The attacks on Edwards being "rich" and out of touch was because that was the central thing to his campaign. He, FAR more than McCain, was trying to paint himself as "one of the people".
As far as the elitism cry.
Money alone does not = elitism. Some of the most "elite" acting people I know are middle class at best. People on this board going "University of :snicker: Iowa" show elitist attitude without any indication of their wealth.
It was never to my knowledge that Obama was painted as some big rich fat cat, he was painted as an intellectual elitist, someone who looked down on simple Americans and their values and was more worried about what academia thought that middle America thought. Advocates on the left tried to sway it to make "elite = rich", despite that not being what the republicans were talking about in any way if you look at context and the things they complained about or pointed to, to try and be able to fight against it (by pointing out his "lower middle class" roots and such) and to attack McCain back (by going "see, HE'S elite, he's RICH!").
