In the race to replace Sen. Sam Brownback (R-Kan.), who's running for governor, Republican Reps. Jerry Moran and Todd Tiahrt continue to find their separation in the polls within the margin of error. A new SurveyUSA poll finds Moran leading by 3 points (Dec. 4-7, 466 GOP LV, MoE +/- 4.6%). Nearly three in 10 likely Republican primary voters remain undecided.

Moran 37
Tiahrt 34
Und 29

Tiahrt has the more conservative voting record and was favored 40%-33% in the poll among voters who identified themselves as conservative. Among moderates, 46% chose Moran and 25% favored Tiahrt.

Moran was first elected in 1996 and Tiahrt came to Congress in historic 1994 freshman class. Both are leaving behind mostly safe districts to run for higher office -- Moran never won with less than 73% of the vote (which came in his first election to Congress), while Tiahrt has held off underfunded challengers this decade with more than 60% each time. The primary will take place in August 2010.
