abandon the side you’d normally vote for
That's part of the liberal delusion we would not vote for a democrat or Republican, because we are not Democrats or Republicans. They do not represent the needs of the marginalized, the working class, They only represent the needs and the wants of the donor class. They only listen to the donor class While our needs get ignored.
You mean those same women and minorities that are currently under threat by the duopoly? The marginalized are still kept marginalized by Democrat as much as they would be a Republican. 50 years of Democrat inaction on women's rights led them to lose their reproductive rights.
