With just three weeks left until Election Day, a new national survey has found the White House race is deadlocked, with both former President Trump and Vice President Harris securing 48 percent support.  The October NBC News survey found Harris lost support over the last month, dropping from 49 percent, while Trump gained support, up from 44 percent in September. About 4 percent of respondents said they weren’t sure who they would vote for or say they don’t want to cast their ballot for either candidate. That number is down from 7 percent in the September survey. NBC noted that while fewer people are unsure about their chosen candidate than in previous surveys, 10 percent say they may change their mind before the election. As the Harris campaign rolls out its efforts to gain Black supporters, the survey found that she enjoys much greater support than Trump. Among Black voters, Harris leads with 84 percent support to Trump’s 11 percent. She also leads among younger voters ages 18 to 34, with 58 percent support to the former president’s 37 percent. Harris leads with 55 percent support among white voters with college degrees, while Trump trails at 41 percent. Trump leads among rural voters, with 72 percent support to Harris’s 23 percent. He also has an advantage among white voters and white voters without college degrees. NBC noted the greatest gap is in gender. Fifty-five percent of women are supporting Harris, and 56 percent of men support Trump. According to The Hill/Decision Desk HQ, Harris has a 2.9 percentage point lead nationally, based on an aggregation of polls. The NBC News survey was conducted Oct. 4-8 among 1,000 voters. It has a margin of error of 3.1 percentage points.
