The Constitution was written specifically to limit the power of the Federal Government. The 10th Amendment was very specific about this:
The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the peopleThis is extremely important. You see if the government isn't explicitly told it can do it, then it is illegal, a ignorant ruling on Obamacare from Chief Justice Roberts not withstanding.
One of the enumerated powers to the Federal Government is to repel an invasion in fact Article 1 Section 8 states
To provide for calling forth the Militia to execute the Laws of the Union, suppress Insurrections and repel Invasions
So by order of the Constitution Militia should be called up, or standing military used to repel the current invasion on the Southern Border.
Notice it never says that it must be a military invasion, merely an invasion. Since we are hearing that 300,000 people are on their way from Central America right now, and an estimated 250,000 Unaccompanied Alien Children by next year, this seems like the perfect time.
Already you are seeing ordinary citizens amassing at the border to repel the tide of disease infected illegal aliens crossing our borders. How long do we have to contend with this? How long until we have truly had enough and demand serious action, then follow through with our demands.
Currently we vent and yell and bitch and wait for an election to be stolen like the MSSen race. Why? Demand action, fore recalls, If Congress doesn't want to act, begin to force your Governor and State houses to send National Guard troops down.
This will not stop until we force it to stop. This can not stand. Do not be the generation that gave it away. Remember they will not go easily, that is fine, after all the blood of patriots and tyrants is the natural manure of the tree of liberty.
