@revelette1,
It's a bush very much worth beating. A person has to be rather dim or tragically unaware of what has happened to the right over the last 50 years to hold that corruption and a lack of affinity for democracy are equivalent in both parties. But it's a simple (and terribly lazy) formulation that appeals to some.
Of course there is corruption to be found in the Dem "establishment" but this present Trump/McConnell/Ryan regime demonstrates how much more corrupt the right now is. Many of the Bernie supporters clearly felt elevated by their political purity but that's very close to a sort of extremism or absolutism - in politics, in religion, wherever it is found - which can lead to a lot of bad stuff, not least the rejection of the practical and realistic.
And because this was/is a divide in the left wing camp, we'll again see it promoted by right wing operatives over the next two years. With any luck, the last two years will have greatly reduced the number of voters who get sucked into that equivalence formulation.
