I suspect that what is happening on the democratic side of the American election will have more of an impact as to whether or not Trump wins than a Republican contested convention.
Bernie Sanders supporters are angry. They are angry that their war mongering corporate empire is built for the rich while the poor rot. They are angry at the life time of debt education requires. They are angry at the ongoing racism, sexism and elevation of corporate interests above human interests and they are bloody angry at politics.
They are beyond angry at Hillary.
Hillary represents all they detest. The smugness, the corporate connections, the hawkish foreign military platform, the disgusting acquiescence to Israel, the peddling of special wealth interests. The super delegate fiasco that is built into democratic races to ensure no one like Bernie Sanders can ever win are as corrupt as anything the Republicans are attempting against Trump and those young voters that Bernie is pulling in such massive numbers are hungry for real change, not the watered down crap Hillary is offering.
When Hillary wins the nomination, as I’m sure she will, those Bernie supports will either not vote at all or vote for Trump out of spite. Their radicalism will conclude that America has to actually get a lot worse before the type of political revolution Sanders has stood for can ever see the light of day, and if it means Trump takes America to hell in a hand basket for 4 years, so be it.
