That's the impact of eight years of Klintoon in the White House. He was the most unprincipled President in history and the Dem part lost all principles of honesty and honor while he was their leader.
Also, in the end this is a winner-take-all contest. Now that the dems are being so brazen about doing and saying literally anything to shift that unaware, politically ignorant portion of the population that votes into their column, it is amazing a republican can win a national election at all.
