Harris' evolving role comes as progressive Democrats target Biden over his pro-Israel stance, polls show him in a tight race against Republican rival Donald Trump. While some have knocked Harris's performance as vice president and value to the reelection campaign in the past, she's moved into a starring role. Current and former Harris aides disputed the idea of any difference in policy between Biden, characterizing their efforts as a difference in tone and emphasis. Biden cannot emphasize divisive cultural issues without alienating more conservative voters he needs to win, current and former aides said. If Trump wins white voters, the largest U.S. racial group, for the third election in a row, Biden needs a dominant showing among a diverse set of groups that typically favor Democrats.
