My impression is this, Republicans do things they believe are right. Democrats do things that poll or focus group well.
They both do things for their “sponsors”. Just sometimes have separate sponsors and always play as if they are opposed, instead of a uniparty.

Much of what they is about acquiring and keeping power. Pelosi’s bill was laced with items that would allow rigging the vote on a massive scale. They don’t always push things that poll well, in fact much what they try to ram through is very contrary to what most Americans want.
I'd say "Democrats do as much as they can get away with"
