The latest poll from Middle Tennessee State University shows that former Democratic Gov. Phil Bredesen holds a double-digit lead over Republican U.S. Rep. Marsha Blackburn.

The poll, which was released Thursday morning, revealed that Bredesen has a 10-percentage-point lead over Blackburn in the U.S. Senate race.

Forty-five percent of registered voters said they would pick Bredesen if the election were held tomorrow, while 35 percent said they would choose Blackburn. According to the poll, another 17 percent said they weren’t sure, and the rest declined to answer.

“Bredesen is off to a good start, and Blackburn has some ground to make up,” said Dr. Ken Blake, director of the poll at Middle Tennessee State University. “But neither candidate has a majority, and with 17 percent undecided, four months to go until the primary and another three after that until the general, this is still either candidate’s race to win or lose.”

In the governor’s race, Boyd, Black, Harwell and Dean had favorable ratings, ranging from 30 percent for Boyd and Black to 26 percent for Dean and 23 percent for Harwell.

The poll did note that Republican Bill Lee and Democrat Craig Fitzhugh trail Boyd, Black and Dean with a 16-percent approval.

Meanwhile, President Trump’s approval rating is holding steady, the poll said. Fifty percent of Tennessee voters approve of the job Trump is doing, while 41 percent disapprove, 8 percent don’t know, and the rest declined to answer.

According to the poll, 46 percent think Trump deserves re-election, 44 percent think he doesn't, and 10 percent don’t know or gave no answer.
