Sure, but she could have said, “I’m a Democrat, I support my Party, but I won’t discuss my vote.” It would be clear who she voted for anyway. She could then say she doesn’t agree with all of O’s policies
It wouldn’t have helped much, because Obama is bad juju on the campaign trail right now, but at least it wouldn’t come across as so mealy-mouthed.
The fact that she refuses to acknowledge that she worked for and voted for the man she now claims to oppose exposes her as a liar.
The voting booth is private if you keep it private. She made it public with her lies about not supporting Obama.
