1. President Obama’s chances of winning reelection suddenly look very strong, as Republicans dig in for a long, nasty presidential primary season. On Saturday night, former House Speaker Newt Gingrich trounced Mitt Romney in the South Carolina primary, snuffing out Romney’s hopes of securing the nomination quickly. The GOP race also has turned ugly — and promises to get even uglier — amid revelations that Gingrich had demanded an open marriage from his second wife, and that Romney has stashed up to $32 million in offshore accounts in the Cayman Islands and has been paying a lower tax rate than the vast majority of Americans. All the while, the president gets to remain above the fray as the GOP presidential hopefuls bloody each other.
