Democratic Senate Majority Leader Harry Reid's (right) support fell to 45%, from 47% on October 9. Meanwhile, Sharron Angle (left) sits at 48%, down from 49% on October 9.
Republican candidate Ken Buck (left) leads Democratic Senator Michael Bennet (right) 50% to 46%, a serious sign Bennet may be defeated this late in the election season. Two weeks ago the race was much closer with Bennet at 45% and Buck barely ahead at 46%.
Another race to watch in the Centennial state is for the governorship. A third-party candidate is closing in on the state's Democratic candidate John Hickenlooper (left). American Constitution Party nominee Tom Tancredo (right), a five-term GOP member of the House of Representatives, holds 44%, up from 40% on October 16, while Hickenlooper maintains the upper hand at 47%, up from 45% two weeks ago.
President Obama's former senate spot is up for grabs this year and there looks to be an improved chance it may be captured by Republican candidate Mark Kirk (right), who has a four-point lead at 46%, compared with Democratic candidate Alexi Giannoulias (left), who has 42%. Last week, Giannoulias had 41%, while Kirk held 43%.
Meanwhile, in the state's gubernatorial election, Republican candidate Bill Brady (left) is leading the incumbent Democrat Pat Quinn (right) 44% to 38%. It seems Quinn is taking a hit from two third-party candidates in that state.
Democratic incumbent Senator Patty Murray (right) has a small lead over Republican challenger Dino Rossi (left), 49% to 47%, reversing Rossi's slight 1-point lead in late September.
Incumbent Governor Ted Strickland (left), a Democrat, appears to be four points behind Republican challenger John Kasich (right). Strickland gained a point since October 23 to nab 44%, but Kasich also moved up a notch, maintaining his lead at 48%, up from 47% last week.
