You may have an argument for Mississippi; the rest of the states you mentioned sound to me like hard fought politics as usual.
Expecting incumbent office holders to roll over for challengers is foolish. They won’t do it, and should not be expected to do so.
The Republican party leadership has, in many ways, lost its way. We can agree on that fact.
The same thing could be said for that entity in the 1970s...and Ronald Reagan didn’t walk away from the party. He worked to change it, and it wasn’t easy. But he didn’t just walk out. I suggest we who consider ourselves conservative follow his example.
By the way, it seems as though Reagan was the “pariah” with the establishment, even after he won the Presidency. He just kept going.
My point is that these intraparty political battles will never, EVAH end. Ever. The same thing was happening in the DemonRat party of the 1980s. The Star Wars bar scene that is the DemonRat constituency had massive battles over ideology and what was considered “best” for the advancement of the organization.
The point is there are TWO and only TWO electable national parties. DemonRat and Republican. The former is lost, if not forever, for at least a generation or two. The latter is still salvageable, in my opinion.
Tilt at windmills like Don Quixote if you like; I’d rather do what Reagan did and work within the party that is the electable, most conservative one of the two.
I’ve done my best to answer your question in the time I have.
Why only Mississippi? In Kentucky McConnell attacked his opponent's business practices implying he was a criminal. In Kansas, the establishment got the state medical ethics board to launch an investigation into Wolf that could damage or destroy his career. In both states, and in dozens of others, the establishment has treated the Tea Party with lip service at best, and total contempt for the most part. And now they expect the Conservatives to come back in lemming-like fashion to pull the leaver and send their worthless asses back to DC. And when folks like you march lock-step and do that then that reinforces their contempt and their tactics. So a couple of years from now the establihment will do the same things, ignore the Tea Party once again, and nothing will change.
The very sould of the Republican Party is as stake here. The establishment has made their contempt known and are bound and determined that the Tea Party and true conservatism will never take over the party. Fine. In the immortal words of John Parker, "If they mean to have a war, then let it start here." In Kansas. With Roberts.
