All eyes are on Philadelphia where tens of millions of voters will watch former President Donald Trump and Vice President Kamala Harris explain their positions and debate their differences on Tuesday. This high-stakes moment could be the most consequential one in this truncated presidential election season. No one understands the importance of this debate more than President Joe Biden who ended his re-election campaign following his disastrous performance in the June debate. The only thing that matters now is how each candidate gets to the winning total of 270 electoral college votes.
