The race to replace Bob Corker is looking mighty close. 

Another new poll — this one from Mason-Dixon — shows former Democratic governor Phil Bredesen with a narrow lead over Republican Rep. Marsha Blackburn, 46 percent to 43 percent. Eleven percent of voters are undecided. 

That result, within the poll's margin of error, is particularly noteworthy in a state that voted for Trump by a 26-point margin and hasn't sent a Democrat to the Senate since 1990.

The poll finds that Bredesen, who was a popular centrist as governor, has about the same name recognition as Blackburn but a better favorability rating (43 percent positive/ 18 percent negative compared to her 35 percent positive/ 26 percent negative.) 

He's currently leading among independents (49 percent to 35 percent) and picking off about one-in-10 Republicans. 

The telephone poll of 625 registered voters was conducted April 17 through April 19.
