Chicago (IL) – If Silicon Valley campaign contributions could determine the outcome of the
presidential election, then there would be little doubt who will
prevail today: Barack Obama received five times more donation dollars
than John McCain.     

According to a report published by the Mercury News and the Center for Responsive Politics, Silicon Valley giants have donated substantially more money to the campaign of Barack Obama than to John McCain. Silicon Valley's top 20 tech companies, in terms of revenue, gave Barack Obama $1,434,719 while John McCain received only $267,041. Only three companies in the ranking -  AMD, Robert Half International and Sanmina-SCI – gave more to the Republican candidate than to the Democrat.

The top five Obama contribution sources - Google ($485,961), Cisco Systems ($149,078), Hewlett-Packard ($148,047), Oracle ($134,421), and Yahoo ($100,276) - gave 71% of the $1.7 million in Obama donations in the top 20 ranking. The same companies, with the exception of HP and Yahoo, appear on McCain's top five list, albeit in a different order: Cisco Systems ($80,676), Oracle ($36,586), Intel ($29,663), Sun Microsystems ($21,500), and Google ($20,600). These companies also gave to 71% of the $0.27 million in McCain donations.

The most prominent John McCain supporters include Cisco CEO John Chambers, and former HP and eBay CEOs Carly Fiorina and Meg Whitman who both spoke at the GOP convention. Fiorina was also among McCain’s financial advisors. Google CEO Eric Schmidt recently publicly endorsed Obama, in addition to Symantec’s John Thompson and former Democratic presidential candidate Al Gore who sits on Apple's board.
