Honestly, a candidate like Trump was not an "if" but a "when".

Even if the Dems had won that election, history has shown they they would not have made any real.changes. They would have done nothing to try and prevent something like the Trump Presidency from happening. They wouldnt have tried to fix the rigged gerrymandered districts, they wouldn't have pushed for voting reform, they wouldn't have tried to call put the insane rhetoric being put out by right wing propaganda machines, and they wouldn't have instilled better checks and balances on the presidency that relied on more than the assumtions of common decency, respect, and tradition.

Nah, they would have rested on their laurels for electing the first female president, and be caught with their pants down when the GOP successfully harnessed the resentment of angry white men for being "under the rule" of a black muslim socialist for eight years, and a satanic pedophile child eating woman for 4.
