This cartoon is not exceptionally brilliant because its stating an obvious truth. Its power lies in the fact that it brings home the truth to so many who still think the Republican Party’s chosen candidates (Graham, Kasich, Christie, Bush, Rubio etc) are worth a vote. Nobody should be supporting these traitors and turncoats who have converted the Republican Party into a subset of the Democrat Party.
The real issue though is that these losers do not get it. They still don’t understand why voters don’t like them anymore.
Trump is steadily awakening them to that truth.
Of course its a comment that applies equally as well to most western so called anti-left establishment parties. The UK Conservatives, The Australian Liberals, (doomed under Malcolm Turnbull) and worst of all the NZ Nationals, led by the panty waisted flag changing Mark Textor devotee Helen Key, who is popular mostly because the NZ Labour Party is so dreadfully unpalatable to even far left voters.
