A few of Tuesday's politically related attention-grabbing headlines:
Newt Gingrich was sued by a songwriter from the group Survivor for using without permission the song "Eye of the Tiger" at campaign appearances.
The chairman of Iowa's Republican Party, Matt Strawn, announced he will step down next week amid controversy over the tight-as-a-tick results of the GOP caucuses in which first Mitt Romney, then Rick Santorum were declared the winner.
Romney may have regained momentum in the race but it appeared to come at the price of his approval ratings which have fallen, possibly because of his going so very negative on Gingrich.
Romney was also quoted Tuesday claiming he only went negative in South Carolina because he was outspent two-to-one but he wasn't.
Rep. Dan Burton, an Indiana Republican facing a stiff primary challenge, announced he won't run for re-election, ending a 30-year congressional career.
