Nor do I think Barbara Radnofsky or Ron Kirk will go. Don't think Rick Noriega will, either (though would be highly supportive if he did). No to Chet Edwards as well. Joaquin Castro's time hasn't come yet.
Frankly, Sharp is it. It won't be an uncontested primary -- there's always Gene Kelly -- but Sharp is our best shot at winning the seat. He'll make Ben Nelson look like a progressive if he does, but when the Republicans nominate Dan Patrick or Michael Williams, Sharp will be able to draw off a lot of those "moderates" in the GOP.
Today I would say that I believe it's going to be Dewhurst and a TeaBagger in a run-off in April of 2012.
And Sharp can win if he's up against a TeaBagger, plainly and simply. Sharp can particularly beat The Bowtie, because there are so many racists and bigots in this state that will not vote for a black man no matter how much he panders to the Teas. "Mod" Republicks will split their tickets big-time if Michael Williams is the nominee. And just imagine if the top of the 2012 Texas ballot is Sarah Palin and Michael Williams versus Barack Obama and John Sharp.
Dewhurst will be the even-money favorite in the GOP primary, but don't count out the freak show. They like to send messages even if it means they lose in November (see Angle, Sharron and O'Donnell, Christine and Buck, Ken).
