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. Bernie Sanders (I-Vt.) will reportedly launch a Democratic presidential campaign tomorrow, becoming Hillary Clinton's first official primary rival. More on this tomorrow.
* In Iowa, PPP shows Scott Walker as the early frontrunner in the Republican presidential caucuses, leading the field with 23% support. Marco Rubio is second with 23%, followed by 12% for Jeb Bush. Mike Huckabee and Rand Paul are the only other candidates to reach double digits, with each garnering 10% support.
* Speaking of the Wisconsin governor, Walker's spokesperson said yesterday journalists are not invited to join him on his trip to Israel next month. "Gov. Walker's trip to Israel will be a listening tour," AshLee Strong said.
* Chris Christie was asked this week about his deteriorating standing in public-opinion polls in his home state of New Jersey. Rather than accepting any responsibility at all for his troubles, the Republican governor said it's news organizations' fault: "If you're going to have relentlessly negative coverage from the media, it's going to affect your poll numbers."
* Republicans probably shouldn't have made committee attendance a campaign issue in 2014: "Republican Sen. Marco Rubio missed a closed Intelligence briefing in January to attend a New York City fundraiser, according to records."
* Jeb Bush traveled to, of all places, Puerto Rico yesterday, in an apparent attempt to "reconnect with the Hispanic voters who have overwhelmingly rejected his party in the past two presidential elections." Puerto Rico's presidential primary isn't until March 13, 2016.
* And right-wing neurosurgeon Ben Carson had been scheduled to address the Southern Baptist Convention Pastors' Conference in Ohio over the summer, but Southern Baptists raised theological concerned: Carson is a Seventh-day Adventist. This week, the SBC and Carson "mutually agreed" to cancel his appearance.
