Let's be honest here. If the Democrats had picked a reasonable candidate, someone who wasn't hopelessly tainted with Wall Street money, someone not tied to some of the worst decisions regarding working peoples financial lives and foreign war making in recent history, someone who didn't repel young women voters with her louche spouse this wouldn't be a contest. Instead they have chosen Hillary. If Trump becomes president, no one will be more responsible than the Democrat establishment.
There were alternatives. Kirsten Gillibrand would crush Trump. The endemic corruption of the Democrat establishment makes them blind to how they are perceived by ordinary voters. As a nominally left wing party the Democrats are most responsible for the economic fortunes of the working and middle classes. They have been a chronic failure in this stewardship and no one is more closely associated with this failure than the Clintons. If Trump wins, the people most responsible will be those apparatchiks of the financial industry who 'cleared the field' for Hillary Clinton, which is almost all of the Democrat establishment.
