I actually do think he knows much better than he lets on. In another thread, he stomped his little feet and plugged his ears when it was explained to him that the House Democrats were the ones with the second stimulus proposal and the Dems had even offered to scale back their requests in an attempt to get the Senate Republican to get off their asses and actually address the House bill. Nope...he kept up his lying when, even being shown proof he was incorrect when he maintained it was the Senate Republican advancing the Dem bill, and the House was just ignoring the Senate’s overtures.
Of course, he had it ass backwards and it took days to get him to admit the Republican were the obstructionists, not the House Dems, even after reams of proof were showered down upon him. That’s just lying and is his habit. sadly. He has no need to see truth, just lies.
