Today's installment of campaign-related news items from across the country.
* Bill Clinton has kept a relatively low campaign profile in recent months, but that's about to change: the former president is scheduled to make "his first campaign trip of the year on Jan. 4, attending a pair of organizing events in Nashua and Exeter," two key communities in New Hampshire.
* Speaking of New Hampshire, the Union Leader's publisher, Joseph McQuaid, compared Donald Trump this week to "Biff" from the "Back to the Future" franchise. The Republican frontrunner responded by calling McQuaid "a real lowlife."
* It almost certainly won't happen, but Jeb Bush would love to participate in a debate with Trump -- and no one else. "Donald, I'll take you on one-on-one in the debate," the former governor told a Florida audience this week. "Any time, any place. You name it, I'll do it."
* Speaking of Bush, he continues to pick up former Lindsey Graham supporters in South Carolina.
* Despite his long-standing ties to Josh Duggar and his family, Mike Huckabee is now insisting he "really didn't support" the accused molester.
* Rick Santorum is eagerly reminding the political world that he, unlike his Republican presidential rivals, has been included in propaganda materials published by ISIS.
* Despite a rough winter storm in Iowa yesterday, Martin O'Malley pressed on, hosting a campaign event in the town on Tama. One voter showed up. He remains undecided.
