The reason the Right tends to lose - beside Original Sin and spiritual entropy - is that rightists rarely seek to infiltrate the enemy strongholds. We live and let live.
Rightists tend to be pioneers and libertarians; we seek freedom - hence the predominance of conservatives in the wide open spaces, pursuing independent enterprises. Contrary to the Big Lie about fascism, the extreme right wind tends toward anarchy, not any form of collectivism (which is what fascism is).
Leftists are herders through and through: Ganging up and taking over what the individual conservative producers made is as natural to them as ordering a half-caff soy-milk latte at Starbuck’s.
Walt Disney, Boy Scouts - it happens to them all eventually.
... and the sad corollary to my above is this: Rightists rarely successfully take back what the Left stole from them. Instead, they simply abandon it. That is what the Mormons are doing.
If We The People under Donald Trump are able to take back America from the communists, I will be surprised (joyously surprised, but surprised).
