BEST CASE: Hillary refuses to play ball and instead takes out Harry Reid as Senate majority leader. From that position she launches the insurgency the GOP lacks the power to launch effectively hamstringing Obama from within his own party while the GOP reorganizes under the radar.
Remember: Obama is bringing in so many ex-Clintonistas she too has a card to play, i.e. "I can't be THAT bad, otherwise he wouldn't have hired all my old staffers".
WORSE CASE: The Clintons play ball and leave themselves exposed to political balckmail and Obama gets a free ride without any opposition from the dems of the GOP.
PROBABLE CASE: Hillary will test the waters among the MSM. If she has enough lingering support--or can find enough feckless POS reporters who like a good story regardless of the campaign narrative they painted--she can let it get back to Barry that if he @#$%s with her she's going to make the next 4 years of his life a living hell.
Whether or not she finds the MSM support remains to be seen. But even then, whatever the press said about her during the primaries it's hard to take down Bill because the dems need his "legacy" as world diplomat, budget balancing, welfare reform and all the other myths assigned to him. Barry may or may not be a dirty political street fighter but very few want a serious fight before they're even in office.
Look for Barry to seek a tense 4-year armistice.
