Political wisdom of the Clinton campaign

Looking at the media relations strategy of the Clinton campaign, they never cease to amaze with their skill.

Here’s the headline:
Clinton chairman: Obama would be good running mate

a) I think they really mean it.
b) It positions Hillary Clinton as the President, the winner and the “real” nominee for the Democratic party.
c) Clinton/Obama or Obama/Clinton would be a very strong ticket for their party, hence the friendlier tone between them during the past two weeks.
d) With the success of John McCain, Republicans are starting to lean toward voting for a Democrat instead.
d) I think they’ve grossly underestimated the Obama campaign.
