A storm brewing in Arkansas?

Blanche Lincoln is about to face her party's primary voters in Arkansas on Tuesday. Up against her are liberal Bill Halter and conservative D.C. Morrison. Polling has consistently shown Lincoln leading Halter by around 7 points. Morrison will not top 10% of the vote. Lincoln is clearly trying to get over 50% to avoid a runoff primary, which would tilt the race towards Halter whose supporters are much more motivated to return to vote at a later date. This race and the one in Pennsylvania will clearly show if the anti-incumbent spirit is as strong as pundits have predicted. This is a race to watch.
