Most polling that has been done fails to include all the candidates who will actually be on the ballot in November. A Rasmussen poll on May 18, reported on a four-way race between Barack Obama, John McCain, Ralph Nader and Bob Barr. The poll, which was conducted before Barr became the Libertarian nominee and made a number of high-profile talk show appearances, found that Barr would finish in third place with 6% of the vote, and Nader with 4%.<ref>http://www.rasmussenreports.com/public_content/politics/election_20082/2008_presidential_election/will_third_party_candidates_tip_the_presidential_race</ref> Another poll conducted around that time showed Barr picking up 8% of the vote in [[Georgia]], seriously hurting McCain's chances of winning that state.<ref>http://www.southernpoliticalreport.com/storylink_520_404.aspx</ref>  It should be noted that in the actual elections, third party candidates such as Barr and Nader general have much lower percentage of votes cast for them than they poll before hand.
