Why do we only ever hear about one or two presidential canidates? It is because those who spend the most money or are given the most "donations" by interested corporations get the most advertising and media coverage. The elections need to bring every presidential canidate into the light and not just those who get the most sponsors.
It is up to the voter to be inform themselves of every canidate, but many people are afraid to vote for someone other than who has been highly publicised, becuase they feel like their vote will be "wasted".
I think that this system is unfair. Whoever get paid off by big corporations the most has the highest chance for sucess. This can lead to a path of corruption and favors for these "donating" parties in the white house.
