Promoting radical elements to divide an opposition party in primary elections is not rarfucking. Rush Limbaugh coined a term for this activity - Operation Chaos. The example of this tactic (which is completely legal BTW) in the last election was for the republican voters to support Bernie Sanders in states with open primaries (party elections open to all voters regardless of party affiliation). The Democrats did the same thing in the Republican primary.
So no cigar!
