The tweets may be Trump’s midterm election strategy:

Privately, sources close to the President and the White House say Trump is also increasingly turning to the 2018 midterm elections and has focused on how he can help deliver high turnout numbers among his supporters. Motivation his base is something the President and some of his allies believe will be key to keeping Congress in Republican hands and thus help avoid potential impeachment proceedings from a Democratic House.

Five sources close to the White House offered varying interpretations of whether there is a strategy behind the uptick in Trump’s tweets. But all agreed the activity has served to energize — or reassure — his political base and provides a preview of how Trump plans to approach the upcoming elections.

“He’s only going to rev this up. He’s looking at targets that the base hates,” one source close to the White House said. “The enthusiasm gap between ‘the resistance’ and ‘the base’ is now palpable.”
