And in between those posts, there was a flurry of fuming calls and text messages — a blaring political fire alarm among Trump’s diehard supporters.

“The reality is sinking in that Trump administration is on the precipice of turning into an establishment presidency,” Sam Nunberg, a former Trump campaign adviser, said in an interview early Thursday morning. (snip)

“If AP is correct, Trump base is blown up, destroyed, irreparable, and disillusioned beyond repair,” King tweeted, referencing an Associated Press story on the bipartisan agreement.

He added, “No promise is credible.” (snip)

Breitbart News, the conservative website now run by former White House chief strategist Stephen K. Bannon, quickly became a gathering place for aggrieved Trump backers. Readers congregated by the thousands in the comments section for an article with a bright red headline: “Amnesty Don.” (snip)

“My sense is that he told Chuck and Nancy what they wanted to hear, and they heard what they wanted to hear. I think there could be some mischief-making on the part of Schumer since the White House is walking it back,” said Mark Krikorian, an immigration hard-liner who runs the Center for Immigration Studies, in an interview.

Meanwhile, Fox News host Sean Hannity, who is in regular contact with Trump, directed his ire over the developments not at the president but at GOP leaders on Capitol Hill.

Trump’s conservative critics, however, said his latest gestures reflect his liberal instincts on some issues and his intense desire for popularity.

“He’s always had that itch to liberate himself from the Republican Party,” said William Kristol, a Trump critic and editor at large of the Weekly Standard magazine. “He ran against it in 2015 and 2016, and has attacked it in 2017. He wants to win and doesn’t care about the substance of winning.”

Kristol added, “Democratic voters may loathe Trump, but he could conceivably give them lots of policy victories.”

Democrats say they are focused only on working with the president on areas where they believe they can get what they want in terms of their priorities, including protections for the dreamers and federal health-care subsidies for Obamacare. They have vowed not to trade dreamer protections for Trump’s long-promised wall at the southern border — and in recent days the White House has indicated the two issues do not have to be linked.

On other issues and with this president, many Democrats remain wary.

Donnelly, despite being wooed by Trump and up for reelection next year, said he feels no pressure to vote for the Republican tax plan if he thinks it’s a bad deal.

“If the tax package makes sense, I’ll support,” Donnelly said. “If not, I’ll pass.”
