A detailed national poll (Los Angeles Times/Bloomberg) in late June 2008 shows that, as a candidate for President, Ralph Nader pulls 3 times more votes from McCain than from Obama. This is the opposite of the conventional wisdom.
When Nader and Bob Barr are added to the race, Nader pulls away 6% of McCain's support but only 2% of Obama's support. Barr pulls away 5% of McCain's support and 0% of Obama's support. So having both Nader and Barr in the race reduces McCain's vote by 11% and reduces Obama's vote by only 2%.
