Trump was favored a week ago by the British bookmaker Bet 365 and stood at -188, while his odds at the beginning of the Monday before election day were at -138. Harris’ odds have been reduced from +150 to +120 at the bookmaker.

The smallest spread in the promotion, which American bookmakers cannot participate in, came from offshore bookmaker BetOnline, which had Trump at +140 and Harris at -120.

The collapse comes as the impact of the statement against Puerto Ricans by a speaker at Trump’s campaign rally in New York’s Madison Square Garden spilled into communities in swing states, including crucial Pennsylvania.
