In theory the dems have more open seats but many of them are not really at risk.
So it is the same old, same old scenario where the Senate is split razor thin if you look at the likely wins in the states.
So this makes any truly new developments critical.
The West Virginia Senate seat that Manchin had- a dem obviously- is lost to the dems. Bam. So that is a new development in this cycle. Sherrod Brown in Ohio has been a long time holder of a dem seat but he is at risk, so that is new. And Tester, the dem in Montana, now appears to unexpectedly be running behind.
Things like that.
Ted Cruz will likely win in Texas but it will be uncomfortably close for pubs.
Luntz has declared that Trump will lose as a result of the recent debate. He has been seriously butt-hurt since Trump called him "a low class slob." He got thrown out of republican circles so he leans toward the lefty's for media access now and delivers what they want to hear. Such is life for a low class slob.
