According to you. You don't understand the issue. Of course Perot, Nader, West, et al have a right to run for president. But the bulk of the votes will go to the two major party nominees. If it's close then a third party, or independent, candidate who gets enough votes may cause the nominee of the major party he's most in line with ideologically to lose. Bush and Gore were so close that if the people who voted for Nader had voted for Gore instead then Gore would've won. If Perot hadn't run then Bush Sr. would've gotten most of Perot's 19% and easily beaten Clinton. That's why they're called spoilers. They have no chance of winning but by running they affected the outcome.
