I'm not completely knowledgable about all the parties as there are 6 of them and I just joined the forums today. Those parties have similar views. I'm not saying they agree on everything but I don't suspect there will be 6 parties after a few elections. I could see this happening two ways. One a party evaporates from a lack of support and the remaining supporters move to another similar party, Another way is if two or more parties merger while compromising on certain issues. Like if the anarcho-capitialist movement were to merger with the conservative coalition party to form a free market, Gun rights sort of party with low taxes and support for smaller government. now it wouldn't be perfect as many compromises would have to be made as with taxes which are very different depending on which party you look at. the capitalist movement would likely have to compromise on things like gun laws and drug legalization but these two parties have a lot in common.
