Steve Ballmer, Microsoft.
Amount donated: $80,500
Largest donation: Tie: $15,000 each, to the Republican National Committee and the Democrats’ DNC Services Corp.
You can’t always guess how someone will vote based on what he does with his funds. Ballmer neatly plays both sides, contributing right and left. For example, he has given $5,000 to the Freedom Project, a PAC affiliated with Republican U.S. Representative John Boehner and another $5,000 to the Democratic Senatorial Campaign Committee. And you thought Microsoft’s product roadmaps were hard to read. Ballmer and his wife each donated $50,000 to President Barack Obama’s inaugural celebration in 2008. Chairman Bill Gates, by the way, has given $160,000, 70 percent of which went to Democratic organizations.
