Take a look at those bills...really LOOK at them, and what is in them; then ask what a lot of those items in the bill have to do with COVID relief. The Senate got burned with the first bill presented back in the spring with all of the non-COVID spending that was stuffed into it. Fool me once, shame on you...fool me twice, shame on me. If the House would send a COVID only bill to the Senate, it would have passed by now. Don't begin to tell me that the Dems had no control over it...it's their bill, and they knew they put stuff in it that isn't COVID related, and would never fly.
As for SCOTUS...Obama DID nominate someone. The Senate advised him that they did not consent to the pick (as is their right). Why would the Senate waste time with hearings on a nominee that wouldn't pass the vote on the floor? And let's be honest, if the parties were reversed, you wouldn't have any problem with the Dems doing the same thing.
