Demagogic

Countries which don't follow the instructions of the United States aren't legal states – at least according to demagogic rhetoric.

It's incredible the number of people who follow demagogic idiots that talk of spirituality while filling their pockets with money.

Politicians knew that the law [barring HIV-positive immigrants] would do nothing to stop the spread of AIDS, and that medical experts agreed the law would actually facilitate it. But politicians did know a cheap and demagogic way to "do something" about AIDS.

The desire for politicians who are sincere explains not only the strategic value of demagoguery (and hence the campaign choices of candidates like Trump who may not in fact believe their own demagogic bombast).
