It's quickly reaching the stage where the right need only point to the left and say "just look at the state of them" in order to win elections.
No. It's reached the stage where various right-wing politicians have abandoned even the pretence of integrity or restraint.
They've realised you can say absolutely anything, even something instantly, provably untrue, and if you shout it loud enough then a certain number of people will lap it up.
They've realised you can weather any number of personal scandals and awful behaviour by doing this shit so relentlessly that people can barely keep up, and then excusing yourself with outright denials (even if instantly, provably untrue: see above) or by basically saying, yeah, so what?
They've realised you don't have to adhere to any standard of political discourse or common decency, if you break through them with no semblance of embarrassment or hesitation: that you can stand up there and yell racist, sexist, xenophobic and ignorant mantras, and make obviously fake promises, and - as long as you do it with conviction - people will lap it up.
They've realised that when people are desperate, impoverished or disenfranchised, you don't actually have to improve their lives. You just need to give them permission to blame someone else: the immigrants, the godless lefties, the media.
They've realised that a lot of people aren't interested in lengthly debate about intricate and often boring (in detail) issues of economic policy or international relations, and that these same people are glad of an excuse to opt out. You don't need to engage with all that! The media are fake and we've had enough of experts.
They've realised that their voters need a cop-out, when the promises turn out to be empty and people are worse off than ever, and that cop-out is: the left made me vote for an extreme right-winger. It's not that he offered completely insincere and unrealistic promises of future gain, and it's not that he tapped into some of the nastier aspects of human nature, and it's not that the momentum of rallies, flags, screamed mantras and total certainty appealed to me. Nope. The left weren't nice enough, and whatever I did was their fault.
