In Argentina, nationwide blanket primaries, called PASO (Spanish: Primarias Abiertas Simultáneas y Obligatorias, meaning "Simultaneous and mandatory open primaries"), were established for presidential and legislative elections in 2009 by Law 26,571.
In 2011, 149 minor parties were either closed, or were not allowed to run in specific provinces where they did not meet the requirements.
All parties are granted free airtime during the political campaign to advertisements of a fixed time duration.
Similar systems used by Washington and Alaska were also struck down in subsequent Supreme Court cases.
In response to the aforementioned Supreme Court decision, Washington state voters passed Initiative 872 in 2004 to adopt a "top two" jungle primary; while lower courts, following the ruling in California Democratic Party v. Jones, struck down the initiative, the Supreme Court ruled on March 18, 2008 in Washington State Grange v. Washington State Republican Party et al. that Initiative 872 was at least facially constitutional and could go into effect.
