Vulnerable Senators up for reelection in 2020:


The Senate race will be close, and some contests will be worth watching on November 3. The following are the ten senators who are most vulnerable in these elections.


  1. Doug Jones
  2. Cory Gardner
  3. Martha McSally
  4. Thom Tillis
  5. Susan Collins
  6. Kelly Loeffler
  7. Joni Ernst
  8. Steve Daines
  9. Ed Markey
  10. David Perdue


Possibility of a hung Senate:


Amid the contest of all the senators up for reelection in 2020, will the Senate decision be made on November 3, or will we have to wait even further? Only the Senate rate of Georgia will decide this.

Both seats of Georgia are up for reelection in 2020, and if one candidate fails to get 50% of the votes, runoff elections on January 5 will settle the dust.

On the first seat, David Perdue will be the Republican candidate, who is up for reelection due to the expiry of his six-year term.

However, on the other seat, Kelly Loeffler was appointed as the successor of the former senator Johnny Isakson, who retired during his term in 2019. Twenty-one candidates will contest this seat, which makes it highly unlikely that anyone will be able to get 50% of the votes.

This will basically be a “jungle primary” contest in which all the 21 candidates will run for the seat, regardless of the political party. If this happens, the Senate can remain unsettled until January, which will increase the curiosity of everyone again.

Senators up for reelection in 2020 will be facing the verdict of the Americans on November 3. Will Republicans successfully recapture the Senate, or will Democrats snatch the Senate away from Republicans? Only time will tell. Stay tuned to missed votes to get the latest updates regarding the 2020 elections.
