The long-simmering disconnect between the Republican Party's conservative base and its leaders in government has degenerated into a full-blown schism.

While President Obama accelerates his increasingly radical agenda, the GOP, despite its congressional majority, can barely muster an objection, let alone block his momentum.

Other than to offer a toothless public rebuke of Obama's destructive schemes, what was the point of the 2014 GOP congressional landslide? It's no longer just a small percentage of conservatives questioning the GOP. Our people are furious -- and rightly so.

I've recently shared my opinion that Donald Trump's explosive surge is because of his giving voice to the conservative base's outrage and his refusal to be chastened or muzzled.

Significantly, establishment Republicans are united with liberal Democrats in their contempt for Trump. The latter attribute his popularity to some innate anger of mean-spirited conservatives who are supposedly soaking up Trump's straight talk like bloodsucking vampires. The former refuse to lift a finger against that liberal slander, and some even pile on, saying that Trump supporters are nativists or xenophobes, as opposed to sane patriots determined to protect America's borders and sovereignty.

Let the elites look down their superior noses at us commoners. Be advised, though, that Trump is not the only one railing against the pervasive insanity, including the role that the GOP leadership is playing in it. Sen. Ted Cruz has set his sights on the "Washington cartel" -- the quasi bipartisan ruling class that is presiding over the disgraceful dismantling of the United States as we know and love it. Candidate Carly Fiorina is also speaking eloquently about bringing "outside-the-box" changes to Washington to make a real difference, as opposed to merely slowing down the devastating Obama juggernaut.

It's easy for the ruling class and its enablers to dismiss conservative opposition as misplaced fury, but grass-roots anger is anything but random and cathartic. It is not an eruption of malcontents looking for an excuse to air some deep-seated unhappiness.

Generally speaking, conservatives are optimistic and bullish on America. But they have witnessed assault after brutal assault against the Constitution, our liberties and our values, and they are justifiably mad as hell and are not inclined to take it anymore.

Adding insult to injury, they continue to elect Republicans to office based on their promise they will try not only to stop Obama's momentum but also to reverse it and make real headway toward saving this nation.

Time after time, they deliver instead outright betrayal. They always offer the same excuses. "We're doing the best we can. We're powerless to do much, and if we try, the voters will be angry and we'll never win the presidency."

Well, for a long time, I've held my tongue; I've given the leadership the benefit of the doubt and resisted impugning the party leaders' motives, even when I strongly registered my objection to their perpetual caving. But I can no longer assume the best of people who are not simply failing to retard Obama's agenda but, in many cases, facilitating it.

With the Corker bill, Senate Republicans have effectively forfeited their constitutional power to reject the Iran nuclear deal -- the most dangerous foreign treaty (yes, it's a treaty) in decades. Over the weekend, the ruling class rebuked and punished Cruz for admirably trying to put a wrench in the scheme to resurrect the Export-Import Bank. And don't get me started on the leadership's performance on Obamacare and Planned Parenthood.

The establishment pretends its outrage against Cruz is based on his alleged breach of Senate rules in accusing Senate Majority Leader Mitch McConnell of lying. These self-righteous patricians pretended to be appalled at this unforgivable incivility.

Well, let me ask you: Are you more worried about what Obama is doing to this nation or alleged violations of Senate decorum? If McConnell really lied to Cruz about a matter that affects the well-being of this nation, are you appalled at Cruz or at those shaming him for trying to represent our interests?

Establishment Republicans are not only emulating liberal Democrats in making Obama's job easier but also acting like liberals in placing form above substance. Their faux ire at Cruz's alleged violation of their prissy rules instead of at Obama's agenda is like the liberal media's outrage at the editing of the Planned Parenthood video rather than at its harvesting of the organs of unborn babies. Instead of joining Cruz, Sen. Mike Lee and others in really opposing Obama, like Democrats, they accuse him of being an opportunist who is interested only in his presidential ambitions.

I am unimpressed by self-serving rules of seniority among the ruling class. What I care about is that our interests are properly represented in Washington, especially by those who deceived us with promises that they would govern as conservatives. Now that, my friends, is opportunism.

God bless Sen. Cruz and all others who are trying to govern precisely as they promised and to give conservatism -- and thus America -- a fighting chance. We haven't heard the end of this yet.
