I like this because taken to its logical extreme, it means that all politics will turn into leftists advocating leftist ideas, and conservatives advocating much stronger exaggerations of those leftist ideas in order to make those ideas look silly.
Instead of normal political debates, we would get debates over whether a certain idea is a real proposal or a comically exaggerated version of a real proposal.
Eventually it goes too far. The Republican Party is replaced with the Comically Exaggerated Democratic Party. If you elect them, they raise the minimum wage to $5,000 an hour. Eventually everyone gets the message and decreases the minimum wage, above the Comically Exaggerated Democratic President’s theatrical objections and demands that we think of the children. It is an amazing political coup.
Outcompeted, the Democrats switch to being the Comically Exaggerated Republican Party. Their platform is feeding poor people to bears, then hunting the bears with automatic weapons. The Comically Exaggerated Democratic Party counters with a demand that the entire continental United States be turned into a national park and designated bear habitat, with humans restricted to a small sliver of territory on the southern half of Manhattan island.
Eventually the country is ruled by bears with machine guns. No one can remember exactly what principle they were trying to prove, but everyone is very confident that they proved it.
