The stakes are high for tonight's GOP debate. Some things to watch for: Rick Santorum attacking Mitt Romney; Mitt Romney attacking Rick Santorum; Newt Gingrich attacking Mitt Romney; Newt Gingrich attacking Rick Santorum; Newt Gingrich attacking the liberal media; Newt Gingrich bringing a German Shepherd that can act as backup for attacking Mitt Romney and Rick Santorum as needed; Ron Paul being ideologically consistent; Rick Santorum coming under attack.
Because they've got to pick a nominee soon. Right?
