Former Missouri U.S. Sen. John Danforth witnessed lots changes to politics over his lifetime.

Danforth, added his age 87, who served in the Senate from 1976 to 1995 and as Missouri’s attorney general from 1969 to 1976, was at the cutting edge of turning Missouri from a state that voted for Democrats for statewide posts to a bellwether that was somewhat evenly divided between the parties. But Danforth is now decrying a force that helped Missouri Republicans take unprecedented power throughout state: Former President Donald Trump.

“It's possible to be a Trump Republican. It's possible to be a Reagan Republican. But the two are not compatible. They're inconsistent,” Danforth said in an interview with St. Louis Public Radio. “It's really impossible to be both at the same time.”
