If everyone isn't aware, Rush has said on a few occasions in the past, that he received a letter from Ronald Reagan, back in the early 1990`s. Rush claimed, in that letter, that Reagan passed onto Rush, the mantle of conservative leader. If that's the case, I don't think Rush will ever leave the Republican Party. But I said the same about brother Buchanan too and was very disappointed by Pat's disloyal behavior.
And you had every right to be disappointed by Buchanan, as he bailed out of the party to put his country first.
