I love that idea. You wouldn't even need millions. Ten to twenty thousand would make the point just as well, and would be unassailable by the capitol police.
That many armed patriots, silently and peacefully strolling past the capitol building, would send a louder message than any speech or rally.
Does D.C. have CC reciprocity?
I think so. And when CNN stuck a microphone in someones face, just 3 words would be all that is needed .....
God Bless America!!
