There are plenty people in the Democratic party who would do things differently, but Republicans universally demonize immigrants and if in power would make life much harder for them.

We live in a democracy where there will always be disagreement between people on policymaking. If you didn't disagree with a Democratic politician on anything at all, you're probably in a cult of personality, a la Trump supporters. That in no way means you should stop advocating for the positions you support and voting for candidates that most align with your values.

What we're talking about here is the difference between Democrats and Republicans after that cynical dude at the top said they were the same when they very much are not. If you don't support a Democratic candidate in a 2 way race because you don't support 15% of their positions, you are voting for the Republican, 95% of whose positions you don't support
