In most cases in a race for a position, it is a democrat versus a republican. Take the 2012 Presidential Election. The incumbent, Barack Obama, faced off against Mitt Romney. However, Gary Johnson, former governor of New Mexico, also ran. One of the reasons he didn't do so well is he wasn't a main part candidate.
