Monday's Campaign Round-Up, 5.18.15

Today's installment of campaign-related news items that won't necessarily generate a post of their own, but may be of interest to political observers:
* Sen. Lindsey Graham (R-S.C.) confirmed this morning that he'll officially announce his presidential plans on June 1.
* At a campaign event over the weekend, Graham told a group of Iowa Republicans, "If I'm president of the United States and you're thinking about joining al-Qaeda or ISIL, I'm not gonna call a judge. I'm gonna call a drone and we will kill you."
* Though there were reports last week that Jeb Bush might skip the Iowa caucuses altogether and focus his resources elsewhere, the former Florida governor made clear over the weekend that he intends to compete in the nation's first GOP presidential caucus.
* Rep. Loretta Sanchez's (D) Senate campaign in California is off to a very rough start. Early last week, there were contradictory messages about her campaign's launch, and late last week, Sanchez used a racially charged gesture while referencing Native American Indians. It took a couple of days, but the congresswoman apologized yesterday.
* Republican insiders are reportedly "dismayed" by Hillary Clinton's "durability" as a national candidate. The Washington Post reported that "months of relentless, negative press coverage" hasn't affected the Democrat's ratings much, which in turn is giving GOP insiders "a serious scare."
* In Kentucky's Republican gubernatorial primary, Hal Heiner had largely ignored allegations that rival James Comer abused his college girlfriend, but Heiner changed his mind late last week, launching a new attack ad about the controversy. The primary is tomorrow.
* Karl Rove appeared on NBC on Friday morning and asked whether he's prepared to endorse Jeb Bush. "Well, no I'm not planning to endorse anybody," he replied. "I'm watching."
