Trump’s approval rating is tanking by every indicator that matters.

And into the dirt.

That’s the only indicator that matters.

If any other president had fucked you this hard, they would have been Luigi'd.

It must all be going according to plan.

But it matters to the larger picture of voters who vote "for the lesser evil". If you like ONE thing Trump stands for (if you don't you don't know everything he stands for) and decided that was enough to vote for him, then those others things can be important enough to vote for someone else. If you vote for Trump the person, or Trump the Republican: then it doesn't matter. However there are still more than enough voters who vote for issues as to change the next election.
