Wrong. Check out the results of a half century of uninterrupted liberal control in some of our largest cities, such as Chicago, Los Angeles, New Orleans and Baltimore. Fascist police practices are alive and well in those cities.
This court is functioning just fine with eight justices. Minority petitioners won reversals by a vote of 7-1. Replacing Scalia with someone even more conservative would have made it 8-1.
But yes, replacing Scalia as well as Breyer and Ginsburg (both well past retirement age) with three conservatives would be awesome. Vote Republican. Or stay home like the Bernie Bros.
