Republican Donald Trump has pulled into a virtual tie with Vice President Kamala Harris, according to the final poll commissioned by The Post ahead of Tuesday’s election — erasing a four-percentage point deficit as the race entered October. The survey by Leger found Trump, 78, and Harris, 60, each receiving 49% support among likely voters, with the remaining 2% saying they would back another candidate. Harris has lost two points of support from the Oct. 1 Leger poll for The Post, which showed her leading the 45th president 51% to 47%.
