Open Question: What do I put for my race/ethnicity?

My fathers family is from spain. (spaniard) My moms side is austrian and romanian. does that make me hispanic or white? Alexis Bledel, Cameron Diaz, Adam Garcia... are all hispanic but they are also white.... where do we fit into all this? this is me: http://flickr.com/photos/26332371@N04/2911349348/?edited=1 I'm trying to register to vote... this is one of the questions... Oh my dad was born in colombia... does that matter? He lives in Spain to take care of his parents now.
