Considering what a drubbing Democratic Senate candidates have been taking in Rasmussen polls lately, a 46-all tie in their first look at the open seat race in Missouri sounds pretty good. (In fact, it's not much different from where we began the race in January, when PPP found Carnahan beating Blunt 45-44; the most recent poll of the race seems to be a GQR poll in May, with Carnahan holding a 53-44 edge.) There's a huge gender gap at work here, with Blunt holding a 17-point lead among men and Carnahan holding a 13-point lead among women.
Maybe Roy Blunt has been doing a great job of rehabilitating the Blunt name (although somehow I doubt it, given his frequent attacks on Medicare and his recent comments comparing Democrats to monkeys), as this sample finds him with a 57/33 favorable, better than Carnahan's 52/42. Barack Obama gets a 46/54 approval, and Governor Jay Nixon is at 58/38.
