One political party created the free IRS Direct File program, a popular new technology that allowed anyone to file their taxes directly with the IRS. The other political party dismantled IRS Direct File immediately upon taking power.
Imho, the fact that you can probably guess which party is which is some evidence that the cliche that both parties are the same isn't really true anymore.
I do this, more or less, for my small law firm. Employee and client information are stored in Recfiles and accessed with GNU Recutils. Adding or changing is a pull request, and all sorts of GitHub actions run. Works pretty well!
To please Trump, Instacart fired my pregnant wife Lisa in a cowardly and cruel way because she dared to run for office as a Democrat. Instacart's leadership will try to obfuscate what happened, but Lisa has the truth on her side. I am so proud of her for fighting back.
I get it, your perspective is totally fair. Part of the reason Democrats care only about donors (the Israel lobby is one of those donors) is because of the influence of money in politics, which is a direct result of Citizens United. If they don't care about their donors, they lose. The incentives are pretty straightforward.
There were great campaign finance laws on the books, but Republican-appointed judges have steadily eroded those over the years, culminating in Citizens United. We have to overrule that awful case if we are to ever have working campaign finance laws in this country again. There's only one way to overrule that case, and that's with Democrat-appointed judges. Those judges typically do not answer to donors and so don't have the same incentives you've identified.
This can be fixed with sane campaign finance laws. Every elected Democrat I know is willing to enact those if Citizens United is overruled. And every Democratic-appointed Justice on the Supreme Court would vote to overturn Citizens United. I know it sounds trite, but voting for Democrats again and again, flawed as they are, for generations, is the only way we're going to get out of this mess.
