Democratic gubernatorial candidate Bill White
Toward the end of 2009, former Houston Mayor Bill White abandoned his campaign for Kay Bailey Hutchison's U.S. Senate seat to launch a Democratic campaign to be governor. White's gubernatorial campaign reported raising $25,056,887 from December 2009 through October 23, 2010. White raised $10.3 million (or 41 percent of this money) from 28 mega donors who gave him $100,000 or more. This includes White's senate and mayoral campaigns, which transferred a total of almost $3.7 million to White's gubernatorial coffers. White's other top donors include the Democratic Governors Association, labor unions, energy executives and trial lawyers. Just two donors gave at least $100,000 to both candidates: Houston oilman James Flores and Austin retirees Joe & Teresa Long. Flores and the Longs both backed White this time after supporting Perry in previous elections.
