2. Eric Schmidt

The executive chairman of Google has contributed $73,000 in 2011-2012 so far, leaning to the left with 63 percent donated to Democrats and 37 percent to Republicans.

While the former Google CEO's offerings are more equally distributed between the two parties than those of some other tech titans, Eric Schmidt may be the tech executive who is most comfortable with the Obama administration. He served as a campaign consultant during Obama's first presidential run, has been invited to White House parties and was even included in the President's Council of Advisors on Science and Technology.

1. Peter Thiel

Co-founder of PayPal and early Facebook investor, Thiel contributed $2,634,700 in 2011-2012 so far. He leans to the right 93 percent to Republicans, 7 percent to Democrats.

According to Influence Explorer, this Silicon Valley venture capitalist is the fourth most generous political donor in the country, giving $2.6 million to campaigns and third parties over the past year and a half. Among his sometimes odd libertarian views like having very smart kids not attend college, Peter Thiel supported Texas Rep. Ron Paul's run for president. Thiel has given the major bulk of his donations to super PAC Endorse Liberty, which runs TV and online spots backing Paul.
