There are probably 15 seats now that have a 5 percent chance or more of flipping (6 D's, 9 R's). The D best chances to win these seats probably would be ordered something like: NE, MI, MN, MD, WA, PA, RI, MT, NJ, OH, MO, VA, TN, AZ, NV.
To get to 51, they need 11 out of 15.
wrong math. They need to win 12 out of these 15 to take the senate.
Ya, I forgot Ohio. 30% is about right, for a six seat Dem gain.
That poll also says that close to half of the voters here call the economy their top election issue, more than three quarters think a photo ID should be required to vote and two thirds think ballots should be printed in English only. I think the state is in play.
