The following is from Patterico's Pontifications. He is right that folks should not be assuming anything about this issue. I have pretty good reason to believe at this point that it really is a case of curiousity killed the cat.
Don’t Make Assumptions About the Passport Flap
Regarding the flap over the passports, the Washington Times reports:
The State Department last night said one of the persons responsible for the inappropriate behavior was employed by an information technology firm headed by one of Mr. Obama’s foreign intelligence advisors.
Of course, this doesn’t establish that Obama was behind the snooping — and people are finding tenuous connections between the two firms and each one of the candidates. Just something to keep in mind: we don’t know who’s behind this yet.
