Do you think supporting the president of the US is treason?
What did he do in his first week to kill off goodwill?
Muslim ban, not removing himself from his businesses, attacking anyone that questioned his connections to Russia, stacking the Press Pool with propagandists... I can go on but I'm not looking to write a book. I'll give you that the above, in such a short time, isn't grounds for anyone to abandon him. That being said, for those that were never with him, their wait and see attitude was met with confirmation of their fears. Now we're 6 months in and not only has none of the issues I've just raised been resolved, he's piled onto the dungheap. It's gotten to the point that the military is openly disobeying direct, hand written (Typed?) orders and trying to hide behind a technicality to justify it. The man has lost all legitimacy. Opposing someone that has lost the mandate to rule after offering to respect their position when they were given a mandate isn't hypocritical, it's a recognition of changing circumstances.
Now if tecoyah had offered to acknowledge whoever won the election and started attacking Trump immediately (making factual observations that he lost the popular vote and lied about inauguration crowd size isn't attacking), THEN he'd be a hypocrite. It was closer to a month before he gave up all hope that Trump wouldn't suck at his job. Quick, true but a result of Trump's non-stop scandals rather than a lack of patience.
