Hey, if Hillary is going to demand that Obama debate Democrats who have already lost, then it's only fair to invite Edwards, Biden, Dodd, Kucinich and Gravel too. And while we're at it, let's invite all the still-living previous Democratic candidates like Sharpton, Kerry, Gore, Dean, Kennedy, Jesse Jackson, Ralph Nader, George McGovern, Mondale and any others who are still around and kicking. It can be like those reality shows where they invite all the has-been stars, like Erik Estrada, to live in a house together and duke it out.
