I’m glad to see that Arkansas Lt. Governor Bill Halter is challenging Blanche Lincoln. The challenge will be coming from the left and is exactly what conservative Democratic Lincoln deserves. She was a big part of the reason labor reform did not pass last year and has been obstinate on health care reform. At a certain point, the party has to recognize that the biggest obstacles to achieving progressive legislative goals are not in the Republican Party, but are to be found in conservative Democrats in both the Senate and House. The best way to remove these obstacles or show obstructionists that it is not in their best interest to block the Democratic agenda is through primaries. It’s not an overnight fix, but at least it shows the conservadems that even in places like Arkansas, in the way is not a good place to stand.
