Doomsday, meet Election Day.

Mayor de Blasio said on Tuesday that only the election of Joe Biden as president in November can break the logjam caused by the Trump administration's inaction on congestion pricing, which MTA officials now say it's caused a delay of one year at least in implementing the central business district tolling that is designed to reduce congestion and also raise $1 billion a year for the cash-strapped regional transit agency.

"There is an election in four months," say the mayor, who has made no secret which candidate he favors. "So things could change very soon in terms of the federal government's views on congestion pricing and the federal government's willingness to help New York City."
