Agreed on the 100% part, but this absolutely isn't specific to political parties. They both love giving corporate handouts with no strings attached. I suspect this has more to do with campaign donations than anything else. It's the same with defense spending where we regularly just can't account for millions of dollars.
Even with the PPP, which was fully bipartisan, they claimed to have strings and then just forgave 10 million of them, even though we know many workers never saw the money intended for them. Slightly different situation, but similar things happened with rural internet initatives in the 90s as well
