Chris Christie is America’s least popular governor in two decades.

A full 77 percent of New Jersey voters now disapprove of Christie, compared to just 19 percent who approve, giving him “the lowest approval rating for any governor in any state in more than 20 years,” according to the latest Quinnipiac survey released Tuesday.

“Voters say 48-43 percent that Gov. Christie personally ordered the ‘Bridgegate’ traffic jam on the George Washington Bridge in 2013,” the poll found. They also believe, 71 percent to 22 percent, that he knew his aides were causing the jam.

This historically dismal polling comes at a particularly pitiful time for Christie, who, after debasing himself as a shameless yes man for Donald Trump during the campaign, was forced out of the president-elect’s transition team. He did not get the coveted nomination for attorney general, and is struggling to claim the Republican National Committee chair as a consolation prize.
