Antecedent problem.
Does “his self-serving show” refer to Santorum or Gingrich or Romney?
Watch those nebulous pronouns.
Romney has some liberal leaning territory ahead in the next few primaries and it will be difficult for Newt to get back the momentum after several losses even though more conservative states have their primaries toward the end.
I don't know why Rick can't suspend and jump back in later if Newt appears to be failing.
