A high-stakes Senate race in Indiana is essentially tied, with incumbent Sen. Joe Donnelly, D-Ind. hanging on to a narrowing lead over Republican Mike Braun, a new poll found.
In the NBC News/Marist survey released Wednesday, Donnelly is leading Braun 48-46 percent among likely voters; 7 percent say they are undecided.
Donnelly had a 6-point edge over Braun in September in the same poll.
When Libertarian Lucy Brenton is included in the poll, Donnelly has just a 3-point lead over Braun — the same as September's NBC News/Marist poll.
"Although Donnelly has a numeric 3-point edge over Braun, the proportion of persuadable voters is nearly five times greater than the margin that separates the candidates," said Lee Miringoff, director of the Marist College Institute for Public Opinion, referring to the 14 percent of voters who say they are persuadable, NBC News reported.
The survey's margin of error is plus or minus 5.5 percentage points.
In a Real Clear Politics averaging of recent polls, Braun is leading by less than a percentage point.
Donnelly is one of 10 Democrats running for Senate seats in states President Donald Trump won in 2016. If Democrats want to regain the majority, they have to win in each of those states as well as flip two seats currently held by Republicans, The Hill noted.
