Well another problem is that they raise more money when there is a loathesome Republican in office. So, losing elections is actually very profitable for them.
The system itself is unquestionably broken. But there are more people suffering under harsh Republican rule. Yeah, plenty of people suffer under democratic rule too. Voting democrat won’t fix capitalism, it won’t fix electoralism, it won’t fix anything. But it will keep the incredibly harsh Republican policies that see women lose healthcare, or trans people lose healthcare, or making it legal to run over protestors out of reach—for the time being.
There are objectively worse, more harmful policies for marginalized groups under Republican rule. They shove through hyper conservative judges that strengthen their ability to make these laws. The democrats put judges on benches that will be middle of the road in an attempt to appeal to “fairness,” and yes, that is a problem in and of itself that needs to be addressed. But there is measurable damage done to an already incredibly fucked up system when republicans win.
We need to do more besides voting, no question. But not voting and then not dedicating your life to helping vulnerable people just isn’t nearly acceptable. Anything less than complete devotion to righteous action when railing against voting is completely unconscionable.
