The Democrats’ Senate prospects brighten:
Overall, the Democrats now project as the favorites in seven seats currently held by the Republicans, with anywhere from 3-7 further GOP seats conceivably in play depending on how generous you want to be.
More from WaPo on the ominous outlook for the GOP:
“If you turn the clock back two or two and half weeks, you could make a plausible argument that if a couple of things go our way we will lose three to four Senate races,” said one Republican strategist. “Now we will lose six to eight.” Polling in most Senate races over the past 14 days has shown a five-point decline for the Republican candidate, the strategist said.
