(INDIANAPOLIS) – Governor Pence will formally announce his reelection bid next month. He could become just the second Indiana governor to face a primary challenge.

Fort Wayne car dealer Bob Thomas has said he‘ll decide in July whether to take Pence on in the Republican primary. Thomas has slammed Pence for supporting the so-called Religious Freedom Restoration Act, while some conservative backers have blasted the governor for supporting a follow-up law aimed at defusing charges that RFRA legalized discrimination.

Despite the RFRA blowback, I-P-F-W political scientist Andy Downs says a challenger would be hard pressed to break Pence‘s hold on conservative voters.
