Swing states have been getting all the headlines in the run-up to Election Day, but within them, there are a handful of counties that will determine if Vice President Kamala Harris or former President Donald Trump wins the big prize.

As things stand, Harris is expected to garner a minimum of 226 electoral votes, and Trump 219. Should that hold, Harris would need only 44 electoral votes to reach the magic 270 threshold, while Trump would need 51. That means every vote in every swing county within every swing state counts.
