Well, the voters of Alabama selected a Democrat rather than an alleged child molester to be their senator in the special election of 12-12-17. That's a good thing, but there's a downside.
They only voted that way by around a percent or so margin. That means very nearly half the voters in Alabama that day actually preferred the child molester to represent them, just for the political party advantage.
When the voters are so deluded by party propaganda as to effectively have no ethics, then why is it a surprise that so many politicians are similarly detestable?
