Indiana is set to host its fourth straight competitive Republican Senate primary, and Reps. Todd Rokita and Luke Messer could become the second set of House colleagues in as many years to face off for the nomination.
This one is for a shot at Joe Donnelly, the first Democratic senator seeking reelection in the state since 2004. The 2010 race initially was for the chance to take on Evan Bayh, but his late retirement announcement made it an open seat.
That year, former Sen. Dan Coats’s 39 percent bested a field that included Marlin Stutzman, whom Republicans nominated a month later for the 3rd District special election. Stutzman lost another Senate primary last year to fellow Rep. Todd Young, who went on to defeat Bayh after a late Democratic candidate swap.
Republicans have a 2-1 general election record during the streak, with Richard Mourdock’s defeat of Sen. Richard Lugar in the 2012 primary the only matchup that led to a loss.
The timing of the early May primary has been beneficial for Republicans, whose nominees were able to coalesce support and restock war chests. The next winner will face new challenges: a Democratic incumbent and a Republican in the White House.
