@TG and Jackamok. TG is right, it doesnt matter if you include the words about really meaning it. Shouldnt that be a given with every amendment, law and ruling? But nobody enforces it.
Obummer was ineligible, but some black robe ignored the constitution and swore him in. Why wasnt that black robe disbarred, arrested and tried for treason? Why did the electoral college voters not deny any votes for Obummer? Etc, etc.
So make a 28th amendment, put whatever is necessary in it and they will still ignore enforcing it as it is written.
At best the only chance you have is at the grass roots level. Get in sherriffs, DAs and governors who respect your rights and ignore federal meddling (and willing to pass on federal money). Not a great chance of success but better than the road to destruction your now on.
