Two polls find Klobuchar still has a big lead

Democratic U.S. Sen. Amy Klobuchar is riding high in the polls as she faces her first re-election campaign.

A Public Policy Polling poll released Thursday found she had a 19 percentage point lead over Republican challenger Kurt Bills. A SurveyUSA poll found she was up 21 percentage points.

The PPP poll said 55 percent of voters said they'd likely vote for her and 36 percent said they were leaning toward Bills. Her marks have actually decreased from voters -- two months ago she had a 26 percentage point lead over him. But the pollster said that Bills has become better known in the interim but she remains one of the best liked senators in the country.

"She doesn't have much to worry about this year," the pollster concluded.

Although Klobuchar is known as a worrier, she has largely laid low this campaign season concentrating on senate work rather than campaigning. That may change as Election Day approaches.

Bills, a first-term state representative with campaign coffers dwarfed by Klobuchar's, has struggled to make his name better known among Minnesotans. According to the PPP poll, 59 percent of Minnesotans said they were not sure whether to feel favorably or unfavorably about him.

Last week, Bills released an internal poll that showed him trailing Klobuchar by 14 points. In that poll, 58 percent said they didn't know enough about Bills to make a judgment on him.

"Romney trails among the rich and the poor, among the educated and the less educated. There is erosion in Romney's support among middle-income and upper-income voters, compared to 6 weeks ago," the SurveyUSA/KSTP pollster said.

Although Minnesota has been a battleground state in the past, both the Romney and Obama campaigns have not treated as such this year. Although the 2000 and 2004 presidential elections were close in the state, 2008 was not and Minnesota has the longest unbroken streak of voting for Democratic candidates for president of any state in the nation.
