In firing FBI Director James Comey, the top cop investigating his campaign for possible collusion with Russia as it meddled in the 2016 campaign, Trump seems to have badly miscalculated.

Having instead provoked a hurricane of blowback from both Democrats as well as a growing number of Republicans, Trump has been knocked on his heels.
