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:
* In Wisconsin, Public Policy Polling's latest survey show Gov. Scott Walker's (R) approval rating dropping in his home state to 43%. In a hypothetical 2016 match-up, Walker trails Hillary Clinton in Wisconsin by nine points, 52% to 43%.
* Predictable tensions are becoming more obvious between Walker's team and Jeb Bush's operation, with the latter criticizing the Wisconsinite for switching his positions on some key issues for the sake of political expediency.
* Former Sen. Jim Webb (D-Va.) has kept a relatively low profile lately, but he spoke at the International Association of Firefighters forum yesterday and suggested his 2016 presidential operation will ramp up soon.
* Sen. Mark Kirk (R-Ill.) is generally considered one of the more vulnerable GOP incumbents next year, and in an unexpected twist, the Illinois Republican will reportedly make his recovery from a stroke "a centerpiece" of his re-election campaign.
* Speaking of senators seeking re-election next year, Sen. Lisa Murkowski (R-Alaska) had the least conservative rating among Senate Republicans in the Club for Growth's annual scorecard. It's unclear if the group intends to bankroll a primary opponent against the incumbent.
* In Arkansas, Sen. Tom Cotton (R) isn't up for re-election until 2020, but some of his allies are thinking ahead -- a Republican state lawmaker is working on changing Arkansas law to allow the right-wing senator to run for re-election and run for the White House at the same time (thanks to my colleague Laura Conaway for the heads-up).
* Asked yesterday whether he's broken any laws, Rep. Aaron Schock (R-Ill.) replied, "Well, I certainly hope not. I'm not an attorney."
* And Sen. Lindsey Graham (R-S.C.), gearing up for a presidential campaign next year, conceded yesterday, "I'm always told how much I suck." He added, "I bring some of that on myself."
