Delph is considering joining State Treasurer Richard Mourdock in challenging Sen. Richard Lugar in 2012.
The two are familiar opponents. They faced off in 2002 in a battle that ultimately put Todd Rokita in the secretary of state's office.
Mourdock has won support from conservatives disenchanted by Lugar's voting record. But a Delph entry into the race could split that vote and carry a highly vulnerable Lugar to victory.
It's happened in Indiana before. Rep. Dan Burton won with 30 percent of the vote in a crowded 2010 Republican primary in which rivals argued it was time for him to go.
