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:
* For the second time in less than a week, Sen. Marco Rubio (R-Fla.) is launching a fundraising drive off an unflattering article in the New York Times.
* It's going back many years, but in 1995, Jeb Bush argued in one of his books that public shaming would be an effective way to regulate the "irresponsible behavior" of unwed mothers. He even offered praise for the practices depicted in Nathaniel Hawthorne's The Scarlet Letter.
* In Ohio's closely watched U.S. Senate race, Public Policy Polling now shows incumbent Sen. Rob Portman (R) with a narrow lead over former Gov. Ted Strickland (D), 43% to 41%.
* Sen. Johnny Isakson (R-Ga.) announced this morning that he has Parkinson's Disease, but the Georgia Republican nevertheless intends to run for re-election next year.
* Rick Santorum isn't going to literally skip the Iowa Straw Poll this year, but he's announced he won't spend any money on it, either. (The practical purpose of the Iowa Straw Poll is to serve as a fundraiser for Iowa Republicans.)
* Speaking of Santorum and Iowa, the former Republican senator attended an event in the Hawkeye State on Monday, which attracted literally just one voter. Ouch.
* Ohio Gov. John Kasich (R) hasn't officially announced his 2016 plans yet, but he recently hired longtime Republican staffer John Weaver and Fred Davis -- both veterans of John McCain's campaign team -- which suggests Kasich is moving closer to launching a national bid.
* If Lindsey Graham, who is a bachelor, is somehow elected president, what would the nation do about a first lady? The South Carolina Republican said this week that he envisions a "rotating first lady," including women he knows.
