The replacement of Vice President Harris for President Biden at the top of the ticket has tilted the races for the White House and Congress in the direction of Democrats, though all three fights will be close, according to Decision Desk HQ (DDHQ)/The Hill’s updated analysis of its election forecast. Harris has a 55 percent chance of defeating former President Trump and winning the White House, a sharp turn up from Biden’s 44 percent chance of winning when he left the race and endorsed Harris on July 21.
