Analysis | Trump’s flirts with Democrats and ‘dreamer’ deal, and his diehard supporters are furious

Staunch conservative allies of US President Donald Trump have erupted in anger and incredulity after Democrats late Wednesday announced that the president had agreed to pursue a legislative deal that would protect thousands of young undocumented immigrants from deportation but not secure Trump’s signature campaign promise: building a massive wall along the US-Mexico border.

Nearing midnight and into Thursday, social media accounts came alive as elected officials and activists on the right dashed off tweets and posts to share their shock.

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.

While the initial wave of fury could change direction as new details emerge, the torrent represented the first major break of Trump’s devoted base from the president on a core issue.

Representative Steve King, one of the biggest Republican immigration hawks, issued a dramatic warning to the president after he scrolled through news reports.
