Seeking common ground
One of the dumber ideas that dominate our politics is the idea that both parties share goals, but differ in how best to reach those goals.
They do not.
The modern Republican Party does not want wages to be high, does not want people to be secure in their employment, does not want the average person to receive competent medical care, and so on.
The goals are different.
The assumption of common ground is not helpful unless such ground actually exists.
Are "both sides" interested in everybody who is properly eligible voting? No. So there is no common ground. There could be a compromise (like, "Okay, how about if 50% of black and hispanic and young people can vote?"
but there is no common ground.
If scientists and creationists split the difference and said the Earth is 2.27 billion years old it would not represent common ground. In fact, it would represent something that neither side believes and helps nobody.
