One poll shouldn't necessarily be cause for panic, but the folks in Mike McGavick's campaign must have a sick feeling in their stomach after seeing the trendline in the latest Rasmussen poll. In the last three weeks Cantwell expanded her lead from 6 to 17 points, going from 46% up to 52% while McGavick slipped from 40% to 35%.

I'm sure McGavick's campaign has been in the field as well. The first question is whether they've seen the same trend. The second question is what, if anything, they can do to reverse it.
