Apparently progressive Democrats are getting frustrated by their inability to get Sen. Kyrsten Sinema to commit to supporting their trillions and trillions of dollars worth of left-wing wish list items and they want to know where she stands. So Sinema told them:

Uh oh, the progressives won’t think that’s funny!

A little of both, maybe?

It might turn out that some Democrats would like to be re-elected rather than just do what left-wing progressives want.
