1) Four years ago, Rick Santorum was the insurgent presidential candidate, winning a tight Iowa race over Mitt Romney and taking 11 other states before bowing out. This year, it seems as though Mr. Santorum has been out-conservatived by Ted Cruz and Marco Rubio and out-blustered by Donald Trump; he shut down his campaign Wednesday evening.
2) We're not surprised that Rand Paul also closed down his campaign after a poor performance in Iowa. But unlike Mr. Santorum, Mr. Paul was at one time considered to be a favorite to win the Republican nomination. It never seemed that Mr. Paul was enough of a libertarian to win over the large, enthusiastic base assembled by his father's presidential runs, and he wasn't conservative enough to attract support from the most vocal side of the Republican Party.
3) Republican U.S. senators from Pennsylvania old and new love Mr. Rubio; he picked up endorsements Wednesday from Sen. Pat Toomey – who seems to be staking out a claim with the party's establishment for his own re-election run – and from Mr. Santorum, who had some difficulty this morning nailing down the specifics behind his enthusiasm.
4) It didn't last long. Mr. Trump seemed to be actually gracious in his short speech accepting defeat Monday night in Iowa – and that was apparently all the grace he could muster. The real The Donald has surfaced on Twitter and elsewhere since, saying Mr. Cruz committed fraud to win the GOP caucuses and demanded that he be declared the winner. Huh – sounds like it's tough being a loser, right Mr. Trump?
5) It's bound to be the most delicious endorsement we're going to see in 2016. It probably shouldn't be a surprise that Vermonters Ben Cohen and Jerry Greenfield – you probably know them as ice cream guys Ben and Jerry – are backing the candidacy of Bernie Sanders; besides the geographic connection, the pair has famously supported many progressive causes over the years. And as they have done in the past, there is ice cream involved; Bernie's Yearning is mint chocolate chip, but "all the chips have somehow ended up at the top in one huge slab— just like what happened with most of the financial gains since the end of the recession," Mr. Greenfield wrote in a promotional email. The ice cream, produced by Mr. Cohen and paid for by Mr. Sanders' campaign, will be available to those who enter contests at berniesyearning.com or at a site run by fundraiser Act Blue on behalf of Democracy for America, a progressive PAC founded by Howard Dean.
