A growing number of Senate Democrats appear open to making it harder for migrants to seek asylum in order to secure Republican support for aiding Ukraine and Israel.
This is what the democrats stand for. Unlimited funding for the MIC and border-control, but social issues are not a priority.
Stop voting for the parties of Capital.
No 3rd party candidate has ever influenced the major parties to date. And likely never will. Sanders, an independent ran as a Democrat, and nearly won the nomination. Democrats took notice, and moved left in some material ways. Giving Sanders power in the party via committee membership/leadership. Something no 3rd party candidate will ever achieve.
Stop splitting the vote. Run as democrats till the neoliberals are all but purged. Then we can work to amend our elections and voting so third parties can make sense.
You can do both.
