Trump regards opposition the same way Putin does, and he would love to install Russia's version of "democracy" here. The frightening thing is that he is succeeding, though his work is far from done. Even Russia's infant democracy took a decade or more to smother, ours is much much older and stronger. But look what Trump has done already in less than two years. His political party has been forced to virtually worship him. The independence of the Justice Department is hanging by a thread, and when that goes we enter into some version of a civil war with mass people power needing to mobilize to counter entrenched power.
Never in my 69 years has the presidency itself been defined in such starkly partisan terms. No, neither Nixon or Reagan (or Johnson either if viewed from a Republican perspective) ever defined half the nation as his enemies. Agnew might have gone there had he had a chance, but he fortunately he didn't. The Right wing media has been integrated into the ruling oligarchy now also. Trump is building his regime on the model of a cult of personality with "the leader" capable of no wrong, and any criticism defined as antipatriotic.
