Cruz is not the enemy. Cruz running is not bad for Rand. Trump/Cruz/Carson running is great for the liberty movement as they each espouse some of Rand's views and are bringing them into the mainstream. Trump has led the way on calling out America's interventionist foreign policy as dangerous, Cruz has made the federal reserve an enemy of the base, and Carson has been even more hard line on budget cuts and tax reduction.
The Rubio/Bush wing of the party, the spend more and intervene more candidates have just a combined 13% support. Romney never fell below 20% in 2012, and his adversaries Perry/Cain/Gingrich were much closer to that philosophy than Trump/Cruz/Carson are. Paul in 2007 was split from the rest of the candidates and the party on taxation, spending, size of government, and foreign policy. Rand now has people saying his father's talking points on the stage with him, and those positions could create a winning coalition which just wasn't possible 8 years ago.
Say these guys stayed out, and we had debate stages of Graham/Jindal/Kasich/Christie/Rubio/Bush/Paul/Huckabee/Fiorina/Santorum. There would be 8+ guys on stage disagreeing with Paul on foreign policy and size of government. He'd get drowned out, and while he might be polling higher than he is today, it wouldn't be possible to assemble a winning coalition as candidates dropped out.
Someone has read Predictably Irrational because it's true. Having Cruz in the race sucks but it might actually help Rand because if everyone is moderates and it's just Rand, people a lot of times make decisions on who they can compare which would cut Rand while the moderates are weighed in the choice category. Cruz is pushing the anti-establishment rhetoric the hardest while Trump is demolishing the rest of the establishment over immigration. Cruz is voicing Ron's old positions without being called kooky old man. This helps Rand as he sets for his surge. People like to compare apples with apples, not apples to an orange because then you complicate things and people are simpletons in making judgments.
The biggest threat is not Cruz, Trump or Carson but Rubio. Trump is minimizing Jeb because that has been his mission and I do not know if he will finish Rubio off. Cruz has been riding Trump's coattails for a while and he to will get steamed rolled by Trump when Trump is done with the establishment.
Rand is being patient and rational while a lot of us Rand supporters are in attack mode to let's surge now. Rand is going to peak at the right time and it's coming. I hope he peaks in January after the next two debates especially after the Jan 28 debate.
Carly, Pataki, Sissy Graham, Chrispy Kreme, Santorum, and Kasich will drop out in the coming weeks.
This leaves two establishment candidates remaining: Jeb and Marco.
Socon faction of the TEA party: Carson
Hawk faction of the TEA party: Cruz
Immigration faction of the TEA party: Trump
Fiscal conservative of the TEA party: Paul
Also Paul has been smart creating the Fiscal conservative narrative as others forget being conservative means being smart/efficient with money and not growing debt but eliminating the debt, Paul has challenged the candidates in standing on big spending!
The TEA party might be the vehicle to finally eliminating the establishment. The movement needs to cycle slowly back to fiscal responsibility in which I believe it will. Rand is changing the debate but much thanks goes to his father for laying the groundwork.
You make an excellent observation!
