ST. LOUIS (AP) — Roy Blunt has served in Congress for two decades, but as he seeks re-election to the Senate, it’s uncertain whether his lengthy political career will be a help or a hindrance.

Donald Trump’s rise to the Republican presidential nomination was fueled, in part, by anti-establishment fervor. Even in a solidly red state, Missouri Republicans know that the 66-year-old Blunt is facing a tough challenge from Democratic Secretary of State Jason Kander.

Both must first get past the Aug. 2 primary, but they are focused on November.

The 35-year-old Kander served four years in the Missouri House before being elected secretary of state in 2012.

Blunt also served as Missouri secretary of state, back in the 1980s. He served 14 years in the U.S. House before being elected to the Senate in 2010.
