But Trump’s long and grievance-filled address that night hinted at trouble to come. For months his US presidential election campaign had been praised as tighter, smoother and more professional this time around. Then, when Democrats upended the race by replacing Joe Biden with Kamala Harris as their nominee, the wheels came off.
“The campaign is disciplined; their candidate is not,” said Frank Luntz, a consultant and pollster who has a long track record of advising Republican campaigns. “Their candidate is single-handedly destroying his chance for re-election. This is the weakest Democratic nominee in terms of record in a long time but [Trump’s] insistence on making the attacks personal and vicious are blunting their impact and, in fact, backfiring on him.”
