Vice President Kamala Harris has gained momentum in the presidential race, overtaking Donald Trump in national polling and leading in five out of seven critical swing states following President Biden's withdrawal from the contest. Recent reports from FiveThirtyEight show Harris with a 2.7-point lead nationally, marking an increase from previous weeks, while Trump has only seen a marginal rise. Analysts suggest that Harris's rise is not merely a 'honeymoon period' as Republicans claim, pointing to her consistent lead in key states like Arizona and Georgia. In addition to her polling success, Harris is set to unveil an economic plan aimed at providing substantial tax relief for middle-class and lower-income families. This includes expanding the child tax credit and earned income tax credit, building on measures from the Biden administration. Both campaigns are now focusing heavily on Pennsylvania, a pivotal state for the upcoming election.
