Looking at Real Clear Polices right now, if the current trends hold, Biden will become president. But just BARELY. We are talking a difference of just 3 or 4 electoral votes.
The Senate appears to still be Republican. But the Dems also lost five seats in the house thus far. They'll still have their majority, but it will be diminished.
My big fear now is that it is so close in the swing states with the mail in voting, that Trump may ask the Supreme Court to intervene. Remember how that turned out in 2000?
