Colorado’s Democratic U.S. Sen. Michael Bennet made CNN’s top 10 list of Senate seats most likely to flip in 2022.

What makes Bennet so vulnerable in a state under siege by the Democrat Party? 

The Democrat didn’t face much of a challenge in 2016, with observers writing off his race well before it was over. But in the end he won reelection only by about 6 points. And although Colorado has trended more blue in the last six years, Bennet’s relatively close 2016 margin is a reason not to move this race off the list quite yet.

Bennet ranked #10 in CNN’s list:

  1. Republican Pat Toomey of Pennsylvania
  2. Democrat Raphael Warnock of Georgia
  3. Republican Ron Johnson of Wisconsin
  4. Republican Richard Burr of North Carolina
  5. Democrat Mark Kelly of Arizona
  6. Democrat Catherine Cortez Masto of Nevada
  7. Democrat Maggie Hassan of New Hampshire
  8. Retiring Republican Rob Portman of Ohio
  9. Republican Marco Rubio of Florida
  10. Democrat Michael Bennet of Colorado

If CNN believes Colorado’s seat will remain in Democrat hands, their prediction suggests they see Bennet as a weak senator and candidate who isn’t very popular within his own party.
