She didn't say she support bitcoin.
Not sure if she understands what blockchain really means, but I think she was just expressing her support for the development of new technologies, which include blockchain technology.
Yeah, I think this is pretty much the case, this doesn't really have anything to do with Bitcoin.
Blockchain =/= Bitcoin
I'm not a fan of her (also not a Trump fan), but I'm not able to vote for her anyway since I'm not in the US.
