It's the essence of far-right populism everywhere: criticize anybody doing anything for not doing it perfectly (the fairness or unfairness of the critcism being entirelly irrelevant for them) whilst never actually offering concrete solutions only the pie-in-the-sky "if we get rid of 'bad people' everything will be solved".

If and when they do get power, they either fail miserably at actually governing and get voted out or capture power and then fail miserably at actually governing (the country goes back decades, most people get a lot poorer and often they end up involved in some stupid war as their "blame 'bad people'" technique leads to the innevitable conclusion when applied at the level of relation between nations).
