Our marxist party participates in every election we can to get our faces known by the public and to influence political discourse. It also simply brings in money for the party.
At the same time behind closed doors we acknowledge that it will not be the way to bring change and we try to build the lass consciousness by going to the factories and other workplaces to get the workers on our side. Real change comes from building a workers movement and you do that by staying involved with the workers. We have local action groups to do that who can tackle local problems and get local people to join us.
Basically the politic side is just some PR machine because realistically we will never get in serious positions of powers that way. We are constantly hindered in these ways.
