Excellent reason to abandon voting altogether.
No. Like I said, put your strength into fighting battles you can still win.
The greatest and really only important battle is to start taking back the culture. Conservatives abandoned the battle for the culture at least 4 decades ago. The lost battle against gay marriage and the other problems we presently face are largely a consequence of this dereliction.
As the late, great Breitbart said, “Politics is downstream of culture.” If the culture is lost, the political realm will eventually reflect that, as it should in a democratic society. So if you don’t like political trends, the answer is to fight the culture battle.
