Right now, there are 538 electoral votes so a 269-269 tie is possible. You need 270 to win outright.
I can see more than three outcomes to the election. Some are rather far out but I will list them.
1. Trump wins big but over trown in a military coup funded by Democrat Party. Joint Chiefs rule and appoint a Democrat in Power as acting President.
2. One state ties it up and we have endless recounts until the courts select Harris as the winner.
3. Trump wins but is shot dead on election night by a secret service agent in an accidental gun discharge (or some other accident).
4. Vote is rigged and Harris wins. Biden calls out the national Guard and FBI arrests all who demonstrate. Fox News shuts down Hannity, Watters, Tucker, Megan Kelly, Ingram all arrested for false misinformation, Governor DeSantis also arrested Florida’s charter revoked and Biden appoints an acting Gov.
5. The election is tossed in the present House and a CABAL of Pelosi Democrats and RINO Republicans select Harris with Mitt Romney casting the vote that keeps Trump out.
6. Due to irregularities in election that sees a Harris victory, states leave the union, set up a new CSA and place Trump in as President of the new nation, New Capital in Montgomery Alabama. This time 23 states will form the new nation.
7. Trump wins and is arrested and jailed by the FBI Charged with treason for working with Russia. In gunfight between Secret service and FBI, Melania and Eric and shot. Barron flees to the Hills to lead an insurgency in the Hills of west Virginia.
8. Biden bombs Moscow starting WW III, Putin uses subs to bombard the East Coast. New York gone. Election cancelled as Washington is vaporized along with London and Kiev.
