Former Sen. Dan Coats (R) is in a statistical tie with Rep. Brad Ellsworth (D) in a hypothetical match-up in this fall's Indiana Senate race, according to a Daily Kos poll set to be released Monday.

Coats is considered the GOP establishment's top choice to replace Sen. Evan Bayh (D) and Ellsworth emerged as the main Democratic contender after Rep. Baron Hill (D) said he will not seek the Democratic nod on Saturday.

The Daily Kos/Research 2000 poll was sent around Sunday by the Democratic Senatorial Campaign Committee (DSCC). It showed Coats leading Ellsworth 37 percent to 36 percent with 27 percent undecided among all those surveyed, but the poll has a margin of error of 4 percentage points. 

On the other hand, ex-Rep. John Hostettler (R), who is one of five GOPers seeking the nomination, leads Ellsworth 40 percent to 24 percent with 26 percent undecided.

The surveyed polled 600 likely voters in Indiana from Feb. 22-24. The party breakdown of the 600 likely voters is 41 percent Republican, 36 percent Democrat and 23 percent Independent. 

Even though Hostettler looks more attractive than Coats in the poll, it was taken before Hill ruled himself out of the race and has a high-number of undecided voters, meaning that the results are still up in the air.
