From a purely tactical electoralist perspective, you are better off showing up to vote for down-ballot state and local officials and leaving national ones blank. It's the opposite of what people normally do, which is just not show up if they don't like the national candidates. The parties look at the difference in votes both between candidates and in terms of the overall number cast.

Accelerationism is when you spend the first Tuesday ocurring after a Monday in November gooning on your couch instead of voting to re-elect the guy who's arming genocidaires and spreading blood libel in addresses to the nation.
