It does not matter whose side you are on or which side you are blaming if you blame politicians for your problem and you are acting neurotically. And would do well to seek help before you cause destruction for your household and those around you.
Left or right, planet savers or planet destroyers, Trump or brexit, democrats or republicans, it does not matter. If you pick sides tribally in this you are signalling neurosis in yourself.
Because the leaders who the people elect are a proxy of those people, a direct proxy for them.
These leaders are they are the best representation of you, the people. They are only there because they are the best representation of you. The people this is how democracy works. It finds leadership, which most likely represents those people who elect them. It works perfectly. There is nothing wrong in the mechanism by which democracy works. Yes, there might be something wrong with democracy in and of itself because it selects leaders we often do not want in the end. Nonetheless, these leaders are a proxy for you, the people.
So if you ever complain in public about the leaders you have elected, those who hear you will see you as an idiot because it was you that done it. It was you that created this world. You.
You will be seen as a spoilt child who cannot have their sweeties. And should be treated and disciplined as such. If you're an adult, how do you discipline this child then? Well I would say deny them the vote obviously whatever age they are. Because they are a danger to the community and they have signalled this very strongly, they blame the leaders they elected. Clearly a neurotic activity bordering on psychotic.
If there are no leaders you respect and trust available on the ballot, then you have no choice not to vote at all. If you still vote for the least worst of them, that is no worse than voting for the worst of them when the opportunity is there not to vote at all.
If you persist in voting for a leader where no one on the ballot deserves to be elected, then you have become part of the problem.
Of course, this cuts both ways. If the people of a Nation are on the whole selfless and virtuous, then it's very much more likely that will deliver a proxy for them, which is also selfless and virtuous. Similarly, if the people of a nation are on the whole selfish and ignorant, then it's very much more likely that will deliver a proxy for them which is also selfish and ignorant. So, if you're asking this question, here is the answer for you. There is no real escaping this question and answer only with the intellect.
