Vice-President Mike Pence Could Emerge As President-By Harsha Sankar-(December 2020)

The US Supreme Court could allow US Congress to decide the eligibility of the electors!

On January 6th, 2021,both chambers of Congress can block electors. Both houses can vote on each state's electors to see if the prescribed manner in which they were picked was proper. If there are insufficient number of electors(270) to choose the President, the house will choose on a state by state basis!

On January 6th, if enough electors are deemed ineligible by both houses so that neither candidate gets 270, it goes to the House. However, if neither candidate gets 26 states to choose him/her, then the U.S. Senate selected VP becomes President. That VP would serve as Acting President.
 

This could happen if a few states' House of Representative members oppose both Trump and Biden. There are those who oppose Trump and at the same time feel Biden lacks fitness to be President.
