Sure, yeah

So both parties accept campaign donations and quid pro quo for the support of Political Action Committees that support them.

Both parties are beneficiaries of a toothless Federal Election Committee enabling non-compliance with the stated regulations, with any remaining accountability existing upon shaky legal ground, completely nullified when in front of a court like with Citizens United. there might be enough consensus for a constitutional amendment though.

Both parties trade securities with material non public information that they can influence, representatives and constituents of any affiliation are not pleased with this. But it is a prisoner's dilemma in the legislative process, there might be enough consensus for a constitutional amendment though.

Presidents of both parties have leveraged the pardon power preemptively and at their discretion, unsettling constituents and representatives on all sides. Revealing a discomfort that is enabled by an archaic aspect of the constitution. Go for it, prioritize a campaign to amend that.

You see the common theme here is that you have to prioritize these causes, over simply being a powerless opposition party going to marches for things that will never gain consensus or that the current power in power will never be held accountable for.

The 17th amendment for directly electing our senators was done in a vacuum. And this likely broke many pillars of our constitution by not also addressing what the senators do, and how that chamber interfaces with the rest of the country. Being appointed likely wasn't better, just more cohesive with the rest of this constitution. Right now we see the folly and redundancy of the Presidential nomination and Senate confirmation process to federal agencies and other position. Should probably amend that too.

All good ideas. Let's do them too. Instead of dismissing the differences between the choices we have today as inconsequential.
