You are exactly right, but whether they wish to admit it or not, they that support Cruz are on the same side of history of those who wish to destroy the Constitutional foundation of the nation.
Broadly speaking, there are two main ethoi that infuse American political and social efforts today. The first, is either de jure or de facto to provide American citizenship benefits to the inhabitants of the globe. Redistributing American wealth to the rest of the world is the goal of our politicians, oligarchs, elites and recent immigrants and many other citizens.
Having a foreign born president is fine with liberals, Democrats, many Republicans, illegal aliens and Cruz and his ilk.
The second effort is to ensure the dominance of Islam as the controlling religious and political power.
Almost every action or explanation in public discourse can be tied to one of these two overarching, all encompassing activities.
This will continue, led by all parties. In your lifetime (or your children’s) you will see America bled dry and Islam victorious. Simply chart the velocity of change in all maters politic and social during the last few years and project it. The demographics are against us, the will to oppose is too weak and held by too few.
While D. Trump is the only elite that will speak to this, even if temporarily victorious, a pendulum once swung to the right will pass back through the center to the far left.
The reality IS that this is no longer a Constitutional Republic. It ceased to be that a few decades ago as the subPreme Court set the Constitution aside for 'penumbra rulings'. With the advent of Roberts on the court, it is clear that owned (read blackmailed) judges now rule a usurped We The People. The democrats have achieved what they only dreamt of a few deacdes ago. They ended the Constitutional Republic long ago, and evidence of that is the 1973 Roe ruling which made murder a right for pregnant women, defining pregnancy as a disease for which murder of the alive unborn is an acceptable cure, so long as the pregnant woman wants to be rid of the alive unborn child..
