Bush Pioneers are people who gathered $100,000 for George W. Bush's 2000 or 2004 presidential campaign. Two new levels, Bush Rangers and Super Rangers, were bestowed upon supporters who gathered $200,000+ or $300,000+, respectively, for the 2004 campaign, after the 2002 McCain–Feingold campaign finance law raised hard money contribution limits. This was done through the practice of "bundling" contributions. There were 221 Rangers and 327 Pioneers in the 2004 campaign and 241 Pioneers in the 2000 campaign (550 pledged to try). A fourth level, Bush Mavericks, was used to identify fundraisers under 40 years of age who bundled more than $50,000.
