Absolutely yes! A lot of people aren't even aware that alternatives to the two big parties exist, and other candidates certainly aren't talked about in the media I've seen. Awareness would also help to make the vote more fair. It's also great for comedic value - we had a seven party debate for our general election last year and it was absolutely hilarious.

Unfortunately, I think that US politics is too corrupt for it to ever actually happen. Often the winning candidate is simply whoever spent the most money during the campaign. I also think the two party monopoly kind of reflects US culture; it seems almost capitalistic in the sense that smaller parties, who are worse off in the sense of having less money, are dominated by the larger parties. I find it very similar to how two or three big corporations fight over an industry (e.g. Target vs Walmart, AT&T vs Verizon...)
