All of the polls agree - Pat Roberts is quickly losing support among Kansans.

The latest Rasmussen Reports telephone survey in the state found that the Republican incumbent now leads Democratic Congressmen Jim Slattery 48% to 39%. In May, Roberts attracted 52% of the vote and was up by a dozen points. Any incumbent who polls below 50% is considered potentially vulnerable. The race is particularly interesting given that Kansas has not elected a Democratic senator since 1932.

Roberts leads Slattery 54% to 36% among men and also has the advantage among voters aged 40 and above. The two candidates are essentially even among women and voters under 40 years of age. Among unaffiliated voters, it is Slattery who has a five-point advantage.

Be prepared for Roberts' ratings to fall even lower after he once more votes against renewable energy tax incentives for Kansas small businesses.

Yeah, you heard me - he's voting against tax breaks for Kansas businesses. Don't believe me? Check this out - he already did it.
