Dan Pfeiffer: “Donald Trump also has the lowest approval rating of any president entering a midterm election since Harry Truman.”“Most presidents this unpopular would try to help their party by staying at the White House and out of the news. That’s what Joe Biden, Barack Obama, and George W. Bush did when their numbers were down and their party was in trouble. It’s the obvious move. The less voters focus on the President with whom they are unhappy, the greater the chance that other members of their party can survive.”“Not Donald Trump.”“The deeply unpopular president who started the unpopular war that raised everyone’s costs in an election where prices are the number one issue has decided to be omnipresent on the campaign trail. In October, Trump has held 21 rallies and has at least half a dozen more scheduled before the election.”
