WASHINGTON, D.C.—In an awesome display of action movie MAGA-greatness, Trump walked away from the exploding Republican Party like an absolute legend, without looking back or even flinching. Witnesses say they saw Trump power-walking in slow motion away from the massive explosion as smoldering wreckage and shrieking Republicans rained down around him. "I've never seen anything so beautiful," said Steve Bannon and Nancy Pelosi in unison. Trump supporters and Democrats collectively cheered while the steely-eyed Trump strutted confidently without any indication that he cared about the scorching inferno behind him as it laid waste to all the "losers and second-rate cowards"...
