President Donald Trump’s campaign has all but pulled its advertising out of Florida, as it stakes its relatively small bank account on the industrial northern states that carried him to victory in 2016.

Since the beginning of the fall campaign on Labor Day, Trump has cut $24 million from his national ad budget, while former Vice President Joe Biden has added $197 million. Biden has outspent Trump three-to-one over that time.

Trump is now placing his final bet on just four battleground states: Michigan, Minnesota, Ohio and Pennsylvania. Polls show he’s down in all those states but Ohio, where it’s effectively even.

The president still has $350,275 budgeted to spend on ads in Florida through Election Day, but has canceled $5.5 million in the final two weeks of the campaign, according to data compiled from ad-tracking firm Advertising Analytics.
