Donald Trump shook up his re-election team with less than four months until November’s vote, replacing his campaign manager, Brad Parscale, in an acknowledgment of the president’s diminished standing in nearly all public and private polling since the spring.

Parscale, who was named campaign manager unusually early, in February 2018, will step out of the job and Bill Stepien, currently the deputy campaign manager and a veteran political operative, will take over. Parscale will stay on with the campaign, becoming a senior adviser for data and digital operations.

The move comes as Trump’s advantages as an incumbent president have eroded in the face of a pandemic that has killed over 137,000 Americans and battered the nation’s economy - once Trump’s most powerful argument for re-election. The President has been heavily criticized for his handling of the coronavirus and the halting federal response to it, and Trump’s own public comments have deepened the hole in which he finds himself in national and battleground state polling.
