President Trump’s adviser Newt Gingrich predicted the new president will have to hold “huge rallies” to get around opposition in Congress, especially the Senate, to complete his agenda.

“He has goals that are not compatible with business as usual, and the only way he’s going to get those goals is to go to the American people over and over,” Gingrich told reporters in the Capitol on Friday, guessing that Trump would be back on the stump by spring. “I think that he will have to continually rouse the country — this is pure Reaganism.”

Gingrich surmised that Trump would target “specific states” to put pressure on certain senators, and adopt a stance of “cooperate but not compromise.”

He guessed that Trump would start by undoing as many as 200 of former president Barack Obama’s executive orders in the first few “phenomenal” days.

But there’s one that Gingrich doesn’t believe Trump will undo as forcefully as expected: the Deferred Action for Childhood Arrivals order that has allowed certain young undocumented immigrants who were brought to the country as children apply for permits to defer their deportations in order to work or attend school.

“They’re not going to be deported; they’ll never be deported,” Gingrich said, suggesting that Trump would likely refuse to accept any new people under the program, but advising him not to touch those already who have taken advantage of the DACA program to date.

“If he says, ‘we’re not going to accept new people,’ that’s one thing, but there’s 700,000 people … and to threaten them so that they’re all worried about an event that will never happen I think will be a mistake,” he said.
