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:
* Relying on data from Smart Media Group, NBC's First Read reports that Mitt Romney and his super PAC have a 10-to-1 advertising advantage over Rick Santorum and his super PAC in Wisconsin. The primary in the Badger State is a week from today.
* When will Newt Gingrich end his failing presidential campaign? As of this morning, the former Speaker said he'll step aside if Romney has a majority of delegates after the Utah primary in late June. (Of course, if Romney has a majority of delegates by then, Gingrich's plans are irrelevant.)
* Two new national polls show President Obama leading Romney nationally, but by very different margins. The latest Suffolk University poll shows the president up by 10, 47% to 37%, while a new McClatchy-Marist poll shows Obama's lead at only two points, 46% to 44%.
* Nebraska Republicans have tried to force Bob Kerrey's name from the primary ballot over residency questions, but the state Supreme Court yesterday dismissed the case.
* Speaking of candidates with residency questions, Sen. Dick Lugar (R) of Indiana is launching a new ad, hoping to convince his party's right-wing base of his hatred for health care reform.
* And the Democratic Congressional Campaign Committee recruited actor Martin Sheen for a new video, telling voters of the Republican plan to "end Medicare." Sheen, of course, played a Democratic president on "The West Wing."
