I'd like to agree with Mark, but it's made a bit more difficult by the fact that Senator Clinton's web site has a prominent graphic which says "Hillary for President" and her PAC was called "HillPAC."
Anyway, the real reason I'm much more like to use "Hillary" instead of "Clinton" is that I'm generally too lazy to type out her title and it's a way to differentiate from her husband.
I guess the point is - I'll stop when her people stop.
