The most interesting question about the upcoming Conservative Political Action Conference (CPAC) gathering is whether any Republican will have the courage to say what many of them privately believe: the way of extremism is the way to GOP disaster. In this sense, CPAC is Sister Souljah waiting to happen, awaiting a Republican willing to criticize extremism directly to them, as Bill ClintonWilliam (Bill) Jefferson ClintonShould the Rob Porter outcome set the standard? Make the compromise: Ending chain migration is a small price to legalize Dreamers Assessing Trump's impeachment odds through a historic lens MORE did in the Sister Souljah affair.

CPAC offers prime time to the latest flavor of the extremist month, Sen. Ted CruzRafael (Ted) Edward CruzOvernight Health Care: Trump eases rules on insurance outside ObamaCare | HHS office on religious rights gets 300 complaints in a month | GOP chair eyes opioid bill vote by Memorial Day HHS official put on leave amid probe into social media posts Trump, Pence to address CPAC this week MORE (R-Texas), most recently seen peddling his extremist wares by accusing Harvard of being infiltrated by communists, while insulting New Jersey Republican Gov. Chris Christie by not inviting this most electable Republican to speak. Readers of my columns might re-read an older column, about the conservative crack-up, and a newer column, about how Hillary ClintonHillary Diane Rodham ClintonWoman behind pro-Trump Facebook page denies being influenced by Russians Trump: CNN, MSNBC 'got scammed' into covering Russian-organized rally Pennsylvania Democrats set to win big with new district map MORE can turn Texas blue. I also agree with a recent column by my colleague A.B. Stoddard, Time for Change, though I would take her wise views and multiply them by ten.

Republicans have learned nothing and reset nothing. I would add that President Obama has not learned all of the right lessons either, and is dangerously close to overreaching. I thought Roger Ailes had received inspiration until he hired Herman Cain, the Democrat's weapon in their charge that Republicans wage wars against women. And now comes the CPAC convention, which could be the greatest show on earth, either as the prime forum for the extremist wing of the right to remind us who they hate on a given day, or as the prime forum for some smart Republican (Jeb Bush? Bobby Jindal? Marco RubioMarco Antonio RubioColbert: Students taking action on gun violence 'give me hope' Lawmakers feel pressure on guns Florida lawmaker's aide fired after claiming shooting survivors were 'actors' MORE?) to warn the right that extremism in the defense of partisanship will give America an eight-year Hillary Clinton presidency (a thrilling prospect for yours truly).

Can you believe Ted Cruz saying that Harvard is infiltrated by communists? Where do Texas Republicans find these guys? (The problem with Harvard is not that it is infiltrated by communists, but that it is infiltrated by a former Harvard president who was once Treasury secretary who expressed condescending views about women while doing hedge fund deals on the side while neglecting his duties to students.)

Cruz recently said one thing I that believe was brilliant. He said Obama's legacy will be elevating Republican leaders (such as himself). This is true. Obama is the political drone, taking annihilating aim at the GOP right, and if the right's hatred of Obama elevates those Republicans who hate him the most, and who are the furthest to the right of the real America, Obama the drone scores a direct hit against his GOP target.

In this sense Cruz is right. If Obama's legacy is elevating Republicans like Cruz, Obama's legacy will be a major political realignment that will include at least 16 years of Democratic presidents (eight for Obama, eight for Hillary) and a liberal Supreme Court (an appetizing prospect for yours truly, which CPAC and Cruz are aiding and abetting) and a Democratic House (an ascendant CPAC advances the triumphant return of Nancy Pelosi).

In a bipartisan mood I recently referred to the extraordinarily popular Christie as the potential GOP Churchill. Christie might well have given the Sister Souljah speech at CPAC, which is why he is the most electable Republican, which is why CPAC fears him and refused to invite him.

I doubt any major Republican will dare to Sister Souljah CPAC, which is why America is on the cusp of a historic political realignment.

In the meantime, why do I suspect that while Ted Cruz will be serving poisoned tea to CPAC, or that in the dining room the Clintons share, Bill will be quietly saying to Hillary, or vice versa, "you do the voter registration rally in Houston, and I will do the fundraiser in Austin"?

Stay tuned.
