(The Center Square) – The most recent polls gauging Colorado’s U.S. Senate and gubernatorial races all show Democratic incumbents leading, but margins vary.

Republican Senate candidate Joe O’Dea is within 1.5 points of incumbent Democratic Sen. Michael Bennet, according to a Trafalgar Group poll released this week.

O’Dea trails Bennet 46.1 percent to 47.6 percent in the poll by the GOP-affiliated firm, putting him within the poll’s 2.9 percent margin of error.

The poll also has Democratic Governor Jared Polis with 49.6 percent support in the governor’s race compared to 42.5 percent who said they would vote for Republican Heidi Ganahl. 

Trafalgar’s poll, which is the most recent poll conducted (between October 30 and November 1), has both Colorado’s U.S. Senate and governor’s races tighter than other recent polls.

A poll released earlier this week by Emerson College Polling/The Hill showed 49 percent of voters backing Bennet and 42 percent backing O’Dea. Polis had 54 percent support compared to Ganahl’s 40 percent, according to the poll, which was conducted from October 26 to 29.

Another poll released this week by the University of Colorado Boulder found 56 percent of respondents said they would vote for Bennet while 42 percent said they would vote for O’Dea. Polis led Ganahl 57 percent to 41 percent in the poll, which was conducted from October 11 to October 19 and has a +/- 4.42 percent margin of error.

Colorado voters will determine both races next Tuesday.
