INDIANAPOLIS (WFFT) - A new statewide poll shows Republican Mike Braun is the favorite for Indiana's U.S. Senate seat, but the race is still too close to call. The IndyPolitics.org - Mason Strategies poll released Tuesday shows Braun leading Senator Joe Donnelly 47 to 43 percent. Libertarian Lucy Brenton had three percent of the vote and seven percent were undecided. Experts say this race is still a virtual tie, especially with the number of voters who still haven't made up their mind. Monday, the Downs Center for Indiana Politics shows Donnelly with a slight lead.
