"Where have Silicon Valley's Republicans gone?" laments CNET News writer Declan McCullagh. George W. Bush backer Tim Draper has switched to the Obama team. There are a few stalwarts: Former Valley CEOs Meg Whitman and Carly Fiorina have campaigned for McCain. And the two are going to be special guests at an election-night party thrown by Lead21. The group, which describes itself as "an influential political organization formed by entrepreneurial business leaders," is coy about the location of the party.But we're not. A source told us it's being held at the rented mansion of Facebook board member Peter Thiel, the former PayPal CEO and founder of Clarium Capital, a hedge fund. Thiel backed Ron Paul in the primaries, but what we really want to know is: What is the gay investor's position on California's proposed gay-marriage ban? Festivities start at 6 p.m. Oh, need directions? Thiel is listed in the phone book. Update: Lead21 chair Sonia Arrison writes:

Just thought I'd let you know that your information source for the location of the Lead21 election party was wrong. It is not at Peter Thiel's home, but it is at a location in the same general area.

If I find out more, I'll let you know. (Photo by Eric Eldon/VentureBeat)
