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:

* Voters in Ohio will head to the polls tomorrow to decide the fate of Gov. John Kasich’s (R) anti-union measure. A new survey from Public Policy Polling shows 59% of Ohioans plan to side with the left and will vote to repeal Kasich’s law.

* Mitt Romney’s presidential campaign has gone back and forth on whether to seriously compete in the Iowa caucuses. National Journal reports that the decision has been made: “Romney will play in Iowa, and he will play to win.”

* Herman Cain declared his allegiance to the right-wing Koch brothers late last week, announce he was “their brother from another mother.”

* Cain and Newt Gingrich participated in a “debate” the other night, hosted by the Texas Tea Party. The two Republican presidential hopefuls apparently agreed on just about everything.

* Rep. Gabrielle Giffords’ (D-Ariz.) recovery continues and in her upcoming book, she writes about her political career, “I will get stronger. I will return.”

* Plenty of observers have been keeping an eye on Sen. Jim DeMint (R-S.C.) to see who he endorses in the presidential race, but it turns out, he won’t back anyone in the Republican primary.

* A new Reuters poll shows President Obama’s approval rating up to 49%, but he still trails Romney in a hypothetical match-up by one point.

* Ron Paul told Fox News yesterday he’s “probably not” going to support the Republican nominee unless he agrees with Paul’s agenda.
