"Has the alt-right led to a more successful cyber-right?"
No, it hasnt. Still barely any success online, of course the 2-3 public figures of the alt-right (i really only know of the original alt-right, that being richard spencer and that other guy, cant recall his name, hes jewish is all i recall) receive a lot of attention. As do the few public liberals many of which are social liberals (i.e. for social programs such as free university, welfare and so on) but those liberals are regularly called alt-right becouse those lying progressives claim to be on the left. They even are brazen enough to claim to be liberals often times.
