OP is right. Manchin gets the blame but 50 others voted against it as well, many who would be willing to cross the aisle but for the toxic partisan environment in this country.
It’s all a horse and pony show. It’s most definitely not just one politician deciding things - they just want you to think that. Ever notice how the villain changes ever few months?
The overlap in donors between GOP and Democrats is insane. Its literally the same few thousand big donors directing policy and the Republican/Democrat thing is just pro-wrestling to entertain the low-information public.
Sometimes I think we're better off when one party or the other has more of a majority in congress, so the whole institution isn't so vulnerable to the wingnuts.
Except that section 174 was fine until Republicans under Trump controlled every aspect of congress and passed the Tax Cuts and Jobs Act (TCJA) in 2017.
That act changed section 174 in this stupid and extremely detrimental way.
So no. It was exactly "one party" (the Republican party) whose fault this is.
