Trump zeroes in on base to overcome reelection obstacles

President Donald Trump is sharpening his focus on his most ardent base of supporters as concern grows inside his campaign that his standing in the battleground states that will decide the 2020 election is slipping. Trump turned his attention this week to “left wing mobs” toppling Confederate monuments and visited the nation's southern border to spotlight progress on his 2016 campaign promise to build a U.S.-Mexico border wall. With his rhetorical turn, Trump is feeding red meat issues to a base that helped spur his upset victory over Hillary Clinton in 2016.
