Two incumbent Democratic senators are now trailing their Republican challengers in key swing states, a new TIME/CNN/Opinion research poll has found.
In Wisconsin, Sen. Russ Feingold is trailing his GOP challenger by six points, the new survey shows. Republican Ron Johnson leads Feingold in that race 51 percent to 45 percent among likely voters, the poll found, with five and a half weeks to go until Election Day.
Meanwhile, in Colorado, incumbent Democrat Sen. Michael Bennet trails GOP challenger Ken Buck in that state’s Senate contest by a five point margin, 44 to 49 percent, the poll of likely voters revealed.
The new survey showed that a Republican is also leading the race for the open seat in Pennsylvania. There, Republican Pat Toomey leads Democrat Joe Sestak, 49 to 44 percent, also among likely voters.
All four polls were conducted via telephone by Opinion Research Corporation from Sept. 17-21. In Delaware, 703 likely voters were queried; 860 in Colorado; 741 in Pennsylvania; and 963 in Wisconsin. The margins of error for Senate and gubernatorial races are roughly +/-3.5%, while demographic margins range from there up toward +/-8.5%.
