WASHINGTON — Senate Majority Leader Harry Reid just took a spin in Wolf Blitzer’s Situation Room on CNN and proffered these caucus-inspired nuggets.

On former White House aide Karl Rove’s Wall Street Journal piece blasting Sen. Barrack Obama’s lack of Senate accomplishments: “Karl Rove, as usual, was wrong.” Reid went on to laud Obama’s work on the ethics bill singed into law this year.

On Reid’s son, Clark County Commission Chairman Rory Reid, leading Sen. Hillary Clinton’s Nevada campaign: “My son is more than 40 years old… I can’t tell him what to do.”

Reid was careful to insert every few moments the point he makes over and over again: He remains neutral in this race, endorsing no candidate. (He quipped last month in Washington that he would endorse after the nomination.)

When Blitzer asked the majority leader to offer up a few hidden facts about each of the three front-runners from his time in the Senate, Reid smiled and obliged.

On Obama and Clinton: “They’re both great writers. She got a Grammy. He got on the best sellers’ list.”

As for former Sen. John Edwards: “The thing about him is the devotion he has to his children,” Reid said. “He really focuses on those children — I’m confident the reason is he lost that boy in the accident.”

For the majority leader known for his zingers, these went down easy.
