Who would Obama like to have running against him? ie who does he think will be the easiest for him to defeat. Obviously, he will do his best to engineer and manipulate the outcome of the primaries to work in his favor.
Pelosi announced that she has big time dirt on Gingrich, but will only release it when the time is right. When is the time right? Why not now?
I may have an overactive imagination, but this is how I see it-Obama views Gingrich as being more defeat able, and is playing his cards to that end.
Having said that, laiv miluchim visurim biyad Hashem. May Hashem have mercy on us.
