In a panel discussion at the University of Colorado after the recent Republican debate, I was asked by a student why she should be a Republican. The question forced me to ask myself the same thing.

I gave the young woman the standard talking points–that Republicans believe in smaller government, individual rights, fiscal responsibility, and free enterprise. But as I drove home, her question–and my inability to respond with any level of real conviction–got me thinking: Does the Republican Party leadership fight for these values and principles today?

After much thought, I reluctantly concluded that the answer is “no.” The proudly socialist Democrats are full of passionate intensity, while the Republican leadership is full of pathetic excuses. After this week’s House GOP “budget deal,” which betrays nearly every promise made to grassroots conservatives since 2010, I have decided it is time to end my affiliation with the Republican Party.

This decision has been incubating over the past 17 years, years of watching the downward spiral of the Party of Lincoln and Reagan into the Party of Democrat Lite.

When I first arrived in the U.S. House of Representatives, I naively believed that it was primarily the Democrats who were committed to open borders. But I quickly learned the entire Republican establishment also supported a policy of immigration non-enforcement.

I was repeatedly pulled into the office of the then-Majority Leader, Tom DeLay, and threatened with dire consequences if I continued to speak out publicly for common-sense immigration policies and true border security – particularly if I was doing so in the districts of other Republican Members of Congress.

For most of those years after 2000, we had a Republican President and a Republican-controlled Congress, but the conservative agenda was largely ridiculed and abandoned.

Across America, in every state, countless hardworking Americans have taken time away from their families and their jobs to volunteer on political campaigns– knocking on doors, making phone calls and talking to neighbors – all to support the effort to beat back the Obama agenda.  In 2010, that grassroots effort resulted in the Republican takeover in the House.  In 2014, it resulted in Republicans sweeping to power in the U.S. Senate – and the largest House majority since Herbert Hoover was President.

Yet, despite these historic gains, nothing changed. The GOP neither advanced a conservative agenda nor checked the radical “transformative” agenda of Barack Obama. We got condescending lip service, and nothing more.

Even in foreign policy the Republican Party leadership has deceived those who elected them by engineering passage of the pathetic Corker/Cardin amendment – which greased the skids for President Obama’s flawed Iran deal to clear Congress without having to meet 67 vote threshold for ratification that the constitution requires for binding international treaties. No one will be surprised if they do the same thing with the controversial Trans-Pacific Partnership.

But times have changed. In 2010, the Republican rank and file stopped drinking the Kool Aid and started demanding accountability. And demanding results. The conservative electorate that elected Republican majorities is tired of capitulation.

The conservative majority in the Republican Party wants leaders who will stand and fight, leaders who will be as passionate about advancing an American agenda as President Obama and the Left are at advancing the global socialist agenda.

Sadly, it has become obvious that the Republican establishment simply has no intention of ever fulfilling promises made in platforms and campaign speeches. To their mind, there are elections, and then there is “governing,” and governing to them means not messing with a gargantuan government on autopilot.

By insulting the grassroots, the GOP leadership has set upon a suicide mission. The problem is that failed leadership is allowing Obama to destroy the Constitution and take the whole country down the drain. Well, count me out.

The Boehner budget deal is the last straw, and enough is enough. I cannot any longer defend this transparently dishonest charade called the Republican Party.

What I will do instead is join the largest political group in the nation, unaffiliated Independents. In Colorado, they outnumber both “major” political parties.

The next day I will begin working my tail off for the next twelve months to organize Independents to help elect Ted Cruz as President of the United States. Cruz is the only candidate who both understands the left’s agenda and has demonstrated the courage to fight for our liberties, our sovereignty, and the survival of constitutional government.
