My point is that Obama doesn’t have plausible deniability. He gets irate when people play in his sandbox. So, his people wouldn’t do something like this without his knowledge and approval.

The fact that they worked on Obama’s election is simply another “bullet point” in the list of their former campaigns and candidates they’ve had.
