In the five days since Republican presidential nominee Mitt Romney was declared by many the winner of the first presidential debate, political watchers have waited to see if polls would shift in response to his performance. And, they did.
What's it like to be a third-party candidate running for president? Ralph Nader can tell us.
"You're excluded from the debates," he says. "You spend an exhausting amount of time, until Labor Day, trying to get over the ballot access barriers. Your petitioners are harassed in the streets; you're subjected to baseless lawsuits by one party or another."
Nader has run for president three times – four if you count the time he ran unofficially. In 2000, he managed to win almost 3 percent of the national vote.
