"You could not invent a better advertisement for the legislative filibuster than what we’re just seeing, a president abandoning rational persuasion for pure, pure demagoguery."

"A president shouting that 52 senators and millions of Americans are racist unless he gets whatever he wants is proving exactly why the framers built the Senate to check his power." 

Said Mitch McConnell, quoted in "McConnell rips Biden’s voting rights speech as ‘profoundly unpresidential’" (NY Post). 

I didn't watch Biden's speech — I can read the transcript — but I did overhear it, and I said out loud, What is he yelling about? Why is he scolding us? He's using a ridiculous "tough guy" voice. 

You can criticize me for not attending to the substance, but he wasn't trying to use substance. He was using emotive sound effects. It was like a Trump rally — but no. A Trump rally would have humor and fun. 

And I don't think Trump ever relied on the argument that you're a racist if you don't agree with him. The anti-Trump rejoinder: Trump never called his opponents racists, because his between-the-lines message was always come all you racists and follow me.
