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 ClintonMueller’s probe doesn't end with a bang, but with a whimper Mark Mellman: History’s judgment Congress should massively ramp up funding for the NIH MORE did in the Sister Souljah affair.

CPAC offers prime time to the latest flavor of the extremist month, Sen. Ted CruzRafael (Ted) Edward CruzDebbie Wasserman Schultz marks 10 years as breast cancer survivor Foreign agent registration is no magical shield against Russian propaganda Let Trump be Trump and he'll sail through 2020 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 ClintonGrassley blasts Democrats over unwillingness to probe Clinton GOP lawmakers cite new allegations of political bias in FBI Top intel Dem: Trump Jr. refused to answer questions about Trump Tower discussions with father 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 RubioRyan pledges 'entitlement reform' in 2018 Richard Gere welcomes lawmakers' words of support for Tibet Dem lawmaker gives McConnell's tax reform op-ed a failing grade 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.
