I'm sorry, but that sounds like an excuse.
Yes, when you have to vote between the lesser of two evils, but one of them is blatantly more evil and incompetent than the other, you're responsible for choosing the more evil and incompetent option and the damage that results.
No system is perfect, and few countries provide morally and politically pure options to vote for in national elections. So an informed and engaged population often needs to vote tactically, understanding that establishments change slowly, and work to elect more effective candidates at local & state level who can work their way up to the national stage.
Voting in the anti-establishment choice just because voters are upset that progress is slow and politics is hard is the stuff of tantrums, and voting adults are supposed to be beyond that.
