Kwa mujibu wa the Wikipedia: A political party is a political organization that typically seeks to attain and maintain political power within government, usually by participating in electoral campaigns, educational outreach or protest actions. Kama vyama vya kisiasa vya Tanzania vinataka kushinda au kuongeza idadi ya wabunge wa upinzani bungeni, basi inawabidi waungane. La sivyo uwezekano wa kuing'oa CCM madarakani ni mdogo. Mifano ipo mingi sana katika bara la Afrika na kwingineko, ambako vyama vikongwe vimeweza kuangushwa tu baada ya upinzani kuungana. Wondwosen Teshome (2009) anaandika, "So far in Africa, opposition parties are rarely successful in ousting the incumbents in elections largely due to theirfragmentation and their failure to form opposition coalitions."
