The single most effective tactic the left has used to defeat the right over the last hundred + years is character attack. The reason why this is so powerful for them is that left wing people, even moderately left people, do not care about the character of their leaders. Everyone knew about Bill Clinton in '92, yet almost no one left of center cared. Everyone knows about Joe Biden's mental state, yet almost no one left of center cares. They don't even care about 'racism' when it's one of their own.
I think this is more complicated than that. Most people will vote with whatever they are given by their party. People vote for anything, at least out of fear of their opponents.
The difference is that all institutions are almost entirely left-wing. They have the leverage to remove people. If it is Turkey, under proto-neo-Ottomanism, it is the left/liberals being removed with any spec that can be found, constructed.
Democracy will always favour left-wing shift. There will always be more people ready to vote to get more stuff from the minority. They stomach increasingly insane social policies for their unaccountable state pension etc. Most people should not be near the helm of society's overseeing. This should be more aparant then ever after witnessing the virus hysteria.
Democracy is a liberal and left-wing system, period. The opposition to that, which is the only one that holds ground, is an authoritarian power. Those of liberal or soy temperament cannot hold their weight in an authoritarian power. If you are of a conservative or right-wing temperament, you cannot hold your weight in a liberal-going-left system, i.e. democracy.
Even if the authoritarian power is communist, all those regimes have ended up shifting further right over time. But, of course, the true authority is the imperfect universal church, led by man, constantly attacked with temptation and subversion, holding back the desires of men and enforcing a moral order.
