Every living former president has higher approval ratings than President Obama -- even his predecessor -- according to a recent poll. The ratings: George H. W. Bush and Bill Clinton, both 84% favorability; Jimmy Carter 56%; George W. Bush 52%; Obama 45% approve, 52% disapprove.

What, me worry? Former State Department flack Marie Harf, promoted but still giving briefings, says her strategic communications team is "totally perplexed" about a New York Times report of a 20% increase in Iranian nuclear stockpiles and calls the concern "absurd."

Sen. Lindsey Graham, R-S.C., indicates he's really serious about running for president. He wants every vote he can get. Graham told a CNN reporter: "If Caitlyn Jenner wants to be safe and have a prosperous economy, vote for me. I haven't walked in her shoes," he continued, adding, "if Caitlyn Jenner wants to be a Republican, she is welcome in my party."
