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 Florida, a new Quinnipiac poll shows Mitt Romney’s lead over Newt Gingrich shrinking to just two points, 36% to 34%, after the former governor led by 12 points a couple of weeks ago. Rick Santorum is a distant third with 13%.

* A new poll from Latino Decisions for Univision News and ABC News shows President Obama with 67% support among Hispanic voters in a hypothetical match-up against Romney. Against Gingrich, the president’s lead is even bigger.

* Gingrich told Fox News yesterday that he won’t compete in additional GOP debates unless audience members are allowed to express approval or disapproval to what the candidates have said.

* Citizens for Tax Justice did a detailed analysis showing the size of the tax cut Romney would give himself if elected.

* Opponents of Wisconsin Gov. Scott Walker (R) did an extraordinary job collecting ballot signatures to force the governor into a recall election, but as the next phase gets underway, Walker still appears to be the favorite. A new poll from Marquette University Law School shows the governor leading all of his potential Democratic rivals by margins ranging from 6 to 10 points.

* Rep. Michele Bachmann (R-Minn.) told Fox News this morning will run for re-election in November, but then quickly walked it back, saying, “I believe I’ll be looking at that, very seriously looking at coming back for a fourth term.”

* Speaking of Minnesota, Public Policy Polling found both Bachmann and former Gov. Tim Pawlenty (R) struggling with low favorable ratings. In hypothetical match-ups against Sen. Al Franken, the Democrat leads Pawlenty by six and Bachmann by 15.

* In Connecticut, former Rep. Chris Shays launched his Senate campaign today, and will take on former wrestling executive Linda McMahon in a Republican primary.

* And in Arizona, Rep. Gabrielle Giffords (D) is departing Congress, and the man she defeated in 2010, right-wing Republican Jesse Kelly, is running to replace her.
