House and Senate Democrats have gone on an anti-Trump rampage on Facebook, their attacks in posts jumping 450 percent after he was elected, according to a new and exhaustive review of congressional Facebook usage.

Virtually nonexistent before Trump’s election, the percentage of opposition postings by Democratic members surged and far out distanced the much lower percentage of Republican congressional rage against former President Obama during his last two years in office, according to the Pew Research Center.
