The president’s campaign is placing more importance on Pennsylvania amid growing concern that his chances of clinching Wisconsin are slipping, Trump campaign sources tell Axios.

Driving the news: Pennsylvania, which has 20 electoral votes, twice Wisconsin’s number, actually has been trending higher in recent public and internal polling, a welcome development for the campaign.

“We used to think Pennsylvania would be harder to secure and Wisconsin was in the bag. Now it’s vice versa,” a Trump campaign adviser said.

But remember: Trump won both in 2016. If Wisconsin slips, he has to make up the numbers elsewhere.
