The Republican Party already suffers from too much of the moderate tail wagging the conservative dog. Blaming "the Party" for the Kavanaugh fiasco is a Democrat trick to suppress our turnout. In reality, the Republican Party as a whole is very solid on his confirmation, with 48/51 Republicans having NEVER EVEN MADE THE SLIGHTEST SUGGESTION THEY WOULD NOT VOTE TO CONFIRM.
Three Senators are holding our Party hostage right now. Imagine picking up 2-3 (and 5-6 is even possible) more seats in the Senate. Collins and Murkowski could be thoroughly marginalized and we could tell them to vote the Party line or lose their precious chairmanships. We can't do that now; we have to kiss their asses.
A Third Party option that siphons off moderates into their own caucus would give them even more power.
No thanks.
The fact is "moderates" weaken the Party message. They're invariably Quislings and traitors, and they go running to the other party when they don't get support from the party that funds them, to the very great accolades of the press when they're punching right, and to completely being ignored when they're punching left.
Moderates don't volunteer. They don't give money. They don't help w/ GOTV efforts. They don't burn down the phone lines. They're a complete burden and giving them even more influence than the completely undeserved amount the already get is ridiculous.
SPOT ON!
