Trump was smarter than Perot in that he knew a third party candidate cannot win. He understood that a more efficient way is to take over one of the existing parties. That’s what he did and that’s why some republicans hate him.
The socialists and communists understood this years ago hence the modern democrat party is now the socialist party. Working from the inside is way more efficient than starting a new party.
Third parties split the vote. Why do you think that the libertarian party of VA received donations from left wing groups a few years ago? The amount of republicans funneled off gave the democrats the win. So instead of a squishy republican we got a total Lib-Tard democrat.
If you don’t like how the Republican Party is run work to change it, don’t vote for the third party that has no chance of winning.
