If you've seen the posting history over the years, that is precisely what he has advocated for - calling for far-left Dems to oust Republicans. The Democrats would have been solidly in control of the US Senate at the time of the Scalia vacancy on the SCOTUS, so of course Obama's pick would have sailed right through and moved the Court solidly left. Think of the number of 5-4 rulings we have had since then that would have been 5-4 the other way, including on immigration policies and the President's powers to control our border and the impact that would have had on this country...not to mention the decades-long negative impact all of the other judicial vacancies being filled by conservatives now that would not have been.
Called out for this before, he non-responds with something like "Keep voting for Lindsey Graham maybe he can get amnesty through" as though this battle would not have already been long lost if what he had advocated had come to pass in Dems taking GOP seats.
Vote for Amash then, any R jersey will do.
