In this file photo taken on Wednesday, Feb. 9, 2011, Sen. Mike Delph, R-Carmel, speaks on a bill during a hearing at the Statehouse in Indianapolis. Delph will not enter the crowded race to succeed U.S. Sen. Dan Coates, who will not seek re-election in 2016. In a statement on his personal blog Tuesday, Sept. 15, 2015, the conservative Delph said the burden of the race and the possibility of living in Washington D.C. would be too much for his wife and five daughters.
