According to the Huffingtonpost,
Nintendo is pretty neutral, though 2 employees of Nintendo donated to the Democrats
Sony is Democrat leaning as the President of Sony Howard Stringer, donated the maximum amounts to Hillary Clinton, the DNC and now switching to Barack Obama. While 88% of its employees donate to the DNC and 12% to the RNC
Microsoft however is back and forth...I guess Bill Gates is still bitter about Bill Clinton going after Microsoft during his administration and caused him to vote Bush in 2000 but Kerry for 2004. However, he's leaning towards John McCain since he has no "Big Tax Hike" that Obama is pushing towards rich folks. He did donate to both but more to John McCain. and 56% of his employees donated to Obama and 44% to McCain.
