New York, Nov 1 (TIWN) Barring a massive polling error or legal tangles that turn the election on its head, it's looking like Democratic challenger Joe Biden has a bit more flex in getting to the winning target of 270 electoral votes than incumbent Donald Trump who is banking on Florida and Pennsylvania to deliver four more years in power.

As you gear up for a longish watch party beginning the evening of November 3 EST (early November 4 IST), here is a handy checklist.  Biden’s best case scenario is to win back three states where Trump staged an upset victory over Hillary Clinton in 2016: Michigan, Pennsylvania and Wisconsin.  If Biden gets all the states Hillary won in 2016, how would the math look at that point? 232 electoral votes. If Biden wins Pennsylvania, Wisconsin and Michigan in addition, he sails comfortably past 270.  The reason pollsters are going so big on Trump’s path through the lens of Wisconsin, Pennsylvania and Michigan is that he won all these three states with razor thin margins against Clinton. Biden will have to do just 1 point better than Clinton did in 2016 to strike a devastating blow.  A lot of narrow Trump wins and some reliably red states in 2016 are suddenly in play: Arizona (11), Texas (38), Georgia (16), Nevada (6), North Carolina (15), Iowa (6), Ohio (18).
