A flurry of new national and swing-state polls released in the past 24 hours, particularly from battleground Pennsylvania, reveals three consistent storylines following the recent presidential debate. Firstly, Democrats find themselves in a stronger polling position than they have been all year, largely attributed to the party's change in the presidential ticket. Secondly, the battleground map appears more favorable for Democrats, particularly in critical Great Lakes swing states like Michigan, Pennsylvania, and Wisconsin. And thirdly, while the presidential race remains tight, with most poll results falling within the margins of error, no party has decisively surged ahead yet.

On the national front, a recent Fox News poll indicates Vice President Kamala Harris holds a 2-point lead over former President Donald Trump among registered voters, standing at 50% to 48%, well within the poll's margin of error of plus or minus 3 percentage points. This marks a slight improvement for Harris compared to the previous month's poll, where Trump was at 50% and Harris at 49%. Despite these shifts falling within the margin of error, it is noteworthy as the Fox poll had Trump leading President Joe Biden for much of the year, with few exceptions.

Moreover, a New York Times/Siena College national poll depicts a dead heat among likely voters, with both Harris and Trump tied at 47%. This parity slightly favors Harris compared to the earlier poll results before September's debate, where Trump held a 48% to 47% edge over Harris. The state polls also reflect Harris performing better in Michigan, Pennsylvania, and Wisconsin compared to Biden's standing over the past year, notably post-debate against Trump in June. In Michigan, polls from Quinnipiac University and Marist show Harris leading Trump by significant margins, while Pennsylvania surveys range from a tied race to a slight advantage for Harris within the margin of error. The outnumber in Wisconsin also lean slightly in Harris's favor across various polls.
