The cautious view among most Republican lawmakers and White House aides is that President Trump won’t follow through with his dramatic threat to close ports of entry at the border.

The big picture: A source who has been talking to Trump about the border situation throughout the past week said that the president remains skittish about doing anything to disrupt the markets. Trump is encouraged by what Mexico is doing to apprehend migrants on their journey to the U.S.

"It’s the markets," the source said. "Closing the border, the markets would plummet."

  • "He’s very well aware that there’s a commercial trucking component that would be devastating on Mexico and would be hurtful to the United States."

Be smart: As with everything Trump ... What is true at 10 p.m. on Wednesday could be false by 7 a.m. on Thursday, depending on who Trump talks to, what he watches, and what kind of mood he’s in.

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.
