What will be Mitt Romney’s legacy? Robert Gehrke sums it up in one word: courage.

Ruben Navarrette: Mitt Romney announced Wednesday he won't run for re-election for Senate seat in Utah .

He says he spent the past seven years as Trump 's most visible foil and most vocal critic of all Trumpism entailed.

He said he's not wrong about ending a career in elected office that spanned more than two decades .

However it plays out and however you view his politics, Mitt Romney should be remembered as a man who recognized a clear threat to our nation’s democracy and, despite the political and personal pain it caused him, demonstrated the courage to hold the line against it. Honestly, that’s not a bad legacy..
