Once again, the Republican Congress failed to repeal Obamacare – even part of it.

Thanks to Sen. John McCain and two other Republicans, a stripped-down Obamacare repeal bill was defeated early Friday, further delaying one of the key planks on which Republicans campaigned in 2016.

It leaves a key component in President Trump's agenda uncompleted.

And there are additional signs of Republican defiance to Trump's plans, especially on immigration.

Politico reported earlier this week several House Republicans are seeking to dodge a straightforward vote to fund President Trump's border wall. Rep. Ilena Ros-Lehtinen, a Hispanic Republican from Florida, has been especially vocal in her opposition.

Some Senate Republicans are also joining the "resistance."

"Wage the Battle: Putting America First in the Fight to Stop Globalist Politicians and Secure the Borders" is a call to action. It is the amazing story of how self-described "manufacturing guy" Paul Nehlen took on Speaker of the House Paul Ryan in one of the most closely followed congressional races in the nation. Nehlen's run presaged the international movement against globalism which reached its climax with the election of President Donald Trump. It's a firsthand look at the development of one of the original "Trump Republicans" and the populist message that is sending shockwaves through the Beltway Right.

Sen. Lindsey Graham of South Carolina essentially dared Trump supporters to vote him out of office, saying he "cannot serve you well" if someone opposes enforcing immigration law against the millions of illegal immigrants in the country.

Paul Nehlen, a Wisconsin businessman who challenged Speaker of the House Paul Ryan for his congressional seat last year, and is challenging again in 2018, says he is disgusted with the conduct of the Republican Congress.

"With a few exceptions, we have a Congress full of spineless jellyfish, unwilling to fulfill their oath of office to protect and defend this country from enemies foreign and domestic," he told WND. "Illegal aliens, whether from visa overstays or illegal border crossers, cannot be effectively deported without a means to keep them out of the country. The border wall proposed by candidate, now President, Trump would stretch from the Gulf of Mexico to the Pacific Ocean. If members of Congress are unwilling to vote to protect American citizens, they must be removed from office."

Nehlen chronicles his 2016 primary challenge to Paul Ryan and lays out a populist, nationalist program for America in his new book "Wage The Battle." The book has received rave reviews from commentators as a forceful challenge to the GOP establishment and the author has been praised as a champion of the movement which made Donald Trump president.

"In 2016, the year of Trump, the great, patriotic businessman Paul Nehlen challenged House Speaker Ryan for the Republican nomination. With the entire establishment GOP against him, Nehlen didn't win . . . but he did force Ryan to double-cross his corporate masters. In his heart, you know President Trump wanted to endorse Paul Nehlen. Much to Ryan's discomfort, Nehlen isn't going anywhere. He will be a thorn in all double-crossing Republicans' side for some time to come." – Ann Coulter, bestselling author

"Self-government only works if you yourself make it work. Otherwise, it is left to cronies and lackeys of the special interests. The difference between liberty and oligarchy is decided by committed citizens like Paul Nehlen, who are not intimidated by the powerful and well-connected; who are not afraid to challenge the status quo." – Ron Maxwell, writer-director of the movies, Gettysburg and Gods and Generals

"Paul is a champion of American values who understands the Constitution and the rule of law. He has the unmistakable qualities of a leader…courage, principal, and resolve. He stands with The Remembrance Project, President Trump and all Americans to halt illegal invasion perpetrated upon our families. I am proud to call him my friend." – Maria Espinoza, cofounder and national director of The Remembrance Project

Nehlen says his message is more important than ever because Speaker of the House Paul Ryan and the GOP Congress are failing President Trump – and it is out of malice, not simple incompetence.

"From Trump's perspective, they are failing President Trump," Nehlen said. "From their perspective, they are succeeding because their efforts are to thwart our America First agenda. Unequivocally, there are a group of UniParty (Republicans and Democrats of the globalist variety) who wish to undermine Trump and get globalism back on track. I applaud Trump's perseverance in the face of their efforts."

However, President Trump also must accept some of the blame, says Nehlen, especially because of some of his personnel decisions and because of his campaign against his own attorney general, Jeff Sessions.

"Listen, personnel is policy," explained Nehlen. "I am no fan of [Director of the National Economic Council] Gary Cohn and a few others Trump has brought into the White House. However, I'm a huge fan of Steve Bannon, Jeff Sessions, Stephen Miller, [Director of Trade and Industrial Policy] Peter Navarro, [Special Assistant to the President] Julia Hahn, and others. I can understand those upset with Sessions. However, I think on balance, Sessions should stay. Nobody has the depth and breadth of experience to lead DOJ in the direction law and order Republicans want it led than Jeff Sessions."

Yet whatever his own missteps, few can deny President Trump is facing subversion and sabotage not just from the GOP Congress, but from within his own administration. Nehlen argues there is battle between nationalism and globalism within the GOP, and the stakes of the battle go far beyond his own candidacy or even the fate of the Trump administration.

"This battle for nationalism is bigger than Trump and Nehlen put together," he declared. "I believe Trump was in the right place at the right time and I'm thankful for his support defeating the Trans Pacific Partnership, which I wouldn't have known the evils of if it weren't for (at the time) Sen. Sessions reporting on the trade deal. My role is happy warrior on behalf of the Wisconsin and American people who deserve to have the playing field tilted in their favor, their safety secured, and their ability to pursue their dreams secured by their elected officials. That's my role in all of this."

Nehlen's work also includes "Hijrah,” the most explosive documentary of the year. It reveals an Islamic invasion like no other before it.
