You are very mistaken. This is a center right country and our population is ripe for the Conservative message. Just consider when an actual Conservative survives the GOP attacks in the primaries, their wins are generally by much bigger margins than the middling GOP candidates.
In the last 2 POTUS elections, the GOP ran progressive candidates and there was not a clear difference between them. The message of “we can run a big government better than they can,” is a losing message.
The populace is ripe for the Conservative message of liberty and freedom. Today’s GOP doesn’t care about promoting those things, they only care about “being in charge of the big government programs.”
Did you ever consider the reason that Democrats always run well to the conservative side of the Dem message? It is because the progressive message is a losing issue when they are honest about it.
