The Democrats declare that anyone who beats them is illegitimate

Back in 2000 the Democrats said that Bush was illegitimate since he didn't really win the election.

Democrats are now saying that Trump is illegitimate since he didn't win the popular vote.

And now Democrats are saying that Kavanaugh isn't legitimate since...well since they say so.

Essentially what this tells us is that Democrats don't believe in Democracy because they only support the results when they win.

If Republican's win via the Constitutional process Democrats say that that's wrong.  Which is just another way of saying that Democrats believe that the law doesn't apply to them.
