Charlie Cook: “The prospects remain very tough for Democrats to hold onto their majority in the Senate, but there is a new scenario emerging–albeit still unlikely–that is turning the majority math a bit on its head.”

“As I have said previously, Republicans need a net gain of six seats to take the majority. The question has generally been whether Republicans just need to knock off six Democratic seats to get to 51, or if they will need to gross seven seats in order to net six. Now there appears to be a real question as to whether Republicans may need to gross eight seats in order to net six, covering for the potential loss of not just Sen. Pat Roberts in Kansas but an open seat in Georgia as well.”

Time reports that Mitt Romney’s digital operation may have been a generation behind President Obama’s effort, “but his email list has proven to be a potent fundraising too for the party as it looks for victory this fall.”

“In the past week, the National Republican Senatorial Committee has emailed the list no fewer than 16 times, many times with emails addressed from Romney himself, while the National Republican Congressional Committee, House Republican’s campaign arm, has used it at least once.”

A new Talk Business & Politics/Hendrix College poll in Arkansas finds Tom Cotton (R) leading Sen. Mark Pryor (D) by eight points in the U.S. Senate race, 49% to 41%.

“We’ve got a tough map. A lot of the states that are contested this time are states that I didn’t win. And so some of the candidates there, you know, it is difficult for them to have me in the state because the Republicans will use that to try to fan Republican turn-out. The bottom line is, though, these are all folks who vote with me.”
