Isn't he promoting TREASON???
Don't we prosecute this crime anymore?
Sorry, but gross stupidity, spouting rubbish, demonstrating ignorance, and lacking sanity do not constitute treason. Treason requires giving aid and comfort to an enemy of the United States (no enemy mentioned; regular criminals don't count, and Mexico is an ally) or levying war against the States (sorry, but this is nothing more than a pipe dream, I see no overt acts beyond general lunacy). And New Mexico has been largely Hispanic since we bought it in 1848.
Actually, I think he is promoting sedition, which is defined as conduct or language inciting a rebellion.
