In 2004, the Socialist Workers Party presidential candidate, Roger Calero, or his stand-in, James Harris, appeared on the ballot in jurisdictions containing 27.2% of the presidential vote cast that year. The party received .03% of the vote in the places in which it appeared on the ballot.

In 2008, the Socialist Workers Party had the same presidential candidate, as well as the same stand-in (the party needs a stand-in when Calero runs, since he is not eligible to be president and therefore some states won’t print his name on the ballot). The 2008 SWP ticket appeared in places that cast 24.7% of the national presidential vote. The 2008 ticket polled .02% of the vote cast in the places where it was on the ballot. The vote total, 7,561, is the second lowest presidential total in the party’s history; only 2000 was lower.
