Evan Bayh in the Senate."](CNN) - Indiana Democratic Rep. Baron Hill told CNN Tuesday he's talking to Democratic state officials about a possible campaign to replace outgoing Sen. Evan Bayh.
Hill acknowledged his House colleague Brad Ellsworth, who announced last week he was running for Bayh's seat, has some support, but said he has received encouragement as well.
"A lot of people are undecided on the state committee. Some are favoring me. Some are favoring Brad," Hill told CNN.
The conservative Blue Dog Democrat was in Afghanistan when Bayh made his surprise announcement last week that he would retire in November. Hill indicated a decision on his own political plans will come in the next few days.
"I think I have to make it sooner rather than later. I think I need to make it this week," Hill said.
The Indiana Democratic Party's Central Committee will select the party's senate candidate, since no candidate filed the needed signatures to qualify for the primary ballot. The committee must wait until after the May 4 primary to select their candidate.
