PolicyMic has this interesting interview with Gary Johnson. It covers his policy ideas, but it also has a great deal about his experience being the Libertarian Party presidential nominee in 2012.
Toward the end, the part of the interview concerning the Electoral College is not fleshed out enough to be clear. The Electoral College system does discriminate against new parties and independent candidates, but only because the U.S. Constitution says if no one gets a majority of the Electoral College, the U.S. House chooses the President. However, a minor party or independent presidential candidate who manages to get a majority of the Electoral College vote is not disadvantaged by that Constitutional provision. In 1992, if Ross Perot had doubled his popular vote, and his increased popular votes had come equally from the ranks of Bush voters and Clinton voters, then Perot would have had a majority of the Electoral College and would have been elected.
