Where in the hell did you get that out of my post. 3rd, 4th and 5th parties are fine with me. But if after 3 or 4 runs at President you still can’t poll above single digits then pack it in.
The networks could fill the debates with marginal candidates, but it would look like the first few weeks of American Idol where they show the auditions of contestants the producers picked for us to laugh at.
If you want to be taken seriously, then run a serious candidate. By your own admission, Nader wasn’t trying or expecting to win. Jeez, wonder why so few people voted for him.
Most of the 3rd party candidates for Presidents have been nut jobs: Perot, George Wallace, Pat Robertson, Nader. Only John Anderson in '80 was close to being mainstream enough to be electable.
Lennon said “if you go carrying pictures of Chairman Mao you ain’t gonna make it with anyone anyhow”. Likewise, if you run on a platform to abolish the IRS, legalize marijuana, return to the gold standard, or any number of other unpopular ideas you aren’t going to get elected. Not because democracy doesn’t work, but because it does.
