Because the alternative was voting for a selfish, thin-skinned, petulant, lying, narcissistic, boastful megalomaniac who committed unthinkable crimes, subverted the republic, committed sedition and treason, ran her own shadow government for personal gain, sold her office as SOS for hundreds of millions through phony "charities," enabled her serial rapist husband to avoid prosecution, and is the whiniest bitch sore loser America has ever known. That's why.
That was the very reason why we didn't vote for Hillary Clinton. And many in the Democratic Party knew it but were too scared by the Clintons' blackmail tactics--including the use of "Arkancide"--to suppress anyone in the Democratic Party opposing her.
