Mason-Dixon just released a bunch of polls on every competitive Senate race. Their findings?
If the election were held today, the Democrats could very possibly take control of the Senate. Democratic candidates are leading Republican incumbents in MT, OH, PA, and RI, and Democrat Harold Ford narrowly leads in the open seat race in TN. That's 5 pick-ups. The Democrats need 6 to take control. But Democratic candidates are also tied in MO and VA. The polls also show Democrats holding on to all our own seats.
All these polls, of course, were conducted before revelations about the Republican leadership's refusal to act on knowledge of a predator in among ranks.
