So Reagan then left the GOP and went off and formed a third party...
Reagan went where a party more reflected his own values.
He left the Democrat Party for that reason.
Reagan would not even recognize the GOP today, because it’s even more to the Left than the Dems were when he left them.
Principled Conservatives will go where their values are extolled and reflected.
They are no longer reflected in the party of the GOP-e, which is become nothing more than a satellite of the DNC. All the Ruling Class cares about is control of the money and the power it gives them. They care not a whit about the fundamental underpinnings that make Conservative principles, nor the Constitution or the Republic they were supposed to uphold and defend.
