Michael Bloomberg will decide to enter the presidential race as an independent. Enough of the electorate dislikes both Hillary Clinton and Donald Trump and the former NYC mayor wins the popular vote in a handful of states. That results in none of the candidates winning a majority in the electoral college.
More confusion is added as both parties dispute the election in Illinois accusing the other side of fraud. Appeals are filed and the case goes to the Supreme Court where no ruling is made because all votes end in a 4-4 tie.
The election goes to the House of Representatives where the Republicans have maintained control. The Republicans can’t bring themselves to vote for Hilary Clinton and dislike Donald Trump enough that no decision is made by Inauguration Day.
Meanwhile, the Senate, where the Democrats now have a majority, selects the next vice-president from the top two vote getters in the electoral college and Hillary Clinton’s running mate becomes acting president until the House can finally come to a conclusion.
