In an election today between Perot, Romney and Obama, Perot would win hands down.
In this election you have two really horrible candidates. At this point I don't know whether or not Goode can win, but the election is not for another 6 months. A lot can happen in 6 months, and you can expect that the mud that is flung out on both Romney and Obama will be neck deep. People are generally dissatisfied with both candidates. They may either not vote at all or turn en-masse to third parties.
This is how the Republican Party got started. It may be how it is ended.
I cannot under any circumstances bring myself to vote for Romney. He is a knee jerk liberal in an empty suit. He has no core convictions except to get elected and to lie, cheat and steal to get the job done. In that sense he is no better than Obama.
Actually it started lower down than president, much more a grass roots response to the Kansas Nebraska Act. It organized to form majorities in most Northern states. Then the presidency with Lincoln.
Third parties trying for the top job today are spoilers at best. As we see on this site lately, they campaign against Romney, not Obama. No hope of actually winning the executive branch, merely preventing the GOP nominee from doing so.
