Who to vote?

It is only few days to our national polls in the Czech Republic and it is being more and more confusing who to vote for undecided voters as me. There are of course working methods of persuasion and propaganda drive, which looks easy to follow, but who is honest to work hard first of all in interest of citizens it is quite unclear.
If it is a bit distinguishable, then it is hard to estimate whether the particular party is able to fulfill their stable and courageous plans. There is always possibility to have a look from the other point of view and consider parties according their representatives, to look what they achieved in past and usually compare if it overrides their political if not private scandals and affairs.
To be disgusted and frustrated by politics as a whole, I would incline for some new parties, who have still a clean slate, not shiny clean, but at least it is only hope, what would lead me to try something 'new', which will really start working if not hard at least harder and honestly.
I know it would be unnatural to believe that new parties will bring a blazing sword of justice, which will fall out on every law, in which shadow speculators, lobbyists of their own interests deride at straight and decent people.
But if there is a little hope of moving forward towards our better society, towards better ourselves, I am ready to stop deceiving and stealing, if you are ready too..
