Something else to think about:
Humility is the among the highest of all virtues. The polarized American political discourse systematically encourages us abandon humility and arrogantly judge and attack those who disagree with us on our party of choice or political opinion. It also encourages us to hate our brothers in our hearts — and that’s an aveira. The left and right are equally guilty of it.
Of course, we should be informed about political issues and seek to apply reason, evidence and Torah perspectives to politics. But we should do so humbly, calmly, patiently and without doing anything to shame anyone else or hurt people’s feelings. If we can’t do that, we shouldn’t talk about politics at all. It’s much better to be completely ignorant about politics and be kind and respectful to everyone than to vote for the “right” party but treat people poorly, commit aveiras and foster negative middos.
All the ideologies in contemporary politics — Liberal, Conservative, Libertarian, Green, Settlers, anti-Zionists, etc. — are compelling to a lot of intelligent people. People tend to be fooled by the falsehood that surrounds them, and we should respect and have compassion even on people with bizarre or false ideas (while responding to them appropriately). We shouldn’t identify too strongly with any party or ideology because none of them are perfectly compatible with Torah. Complete identification leads to arrogance, overconfidence and unwillingness to learn from every person (see Avos) and objectively evaluate evidence.
