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:

* For much of 2011, Mitt Romney ignored Iowa, making only two appearances in the state in the first eight months of the year. Now, however, Romney is going all in with an aggressive new strategy in Iowa, including the launch of a new television ad.

* Romney also hoped to cruise to an easy win in New Hampshire, with minimal investment. Yesterday, however, the former governor began airing a TV ad in the state, despite polls showing him well ahead of his Republican rivals.

* Herman Cain struck a defiant tone at a campaign stop in Ohio, but later said he’d announce whether he’ll stay in the race next week.

* Ron Paul’s campaign released a hard-hitting attack video yesterday, targeting Newt Gingrich. The web-only clip is over two minutes long, and probably won’t be aired in broadcast media.

* A new poll from University of Massachusetts Amherst shows Elizabeth Warren (D) taking the lead over Sen. Scott Brown (R) in Massachusetts’ U.S. Senate race, 43% to 39%.

* For the second time this week, a poll out of Florida shows Gingrich with a big lead in the race for the Republican nomination. Public Policy Polling found Gingrich leading Romney, 47% to 17%.

* In Montana, PPP also found Gingrich leading the Republican field, topping Ron Paul, 37% to 12%.

* Speaking of Gingrich leading at the state level, a poll from a CBS affiliate in Louisiana found Gingrich leading Romney, 31% to 23%.

* In Pennsylvania, the GOP field is not yet set in the race against Sen. Bob Casey, but PPP shows the incumbent Democrat leading all of his likely Republican rivals by double digits.

* In Missouri’s gubernatorial race, Republican businessman Dave Spence is hoping to scare away potential primary rivals by investing $2 million of his own money into his new campaign.

* And as Americans Elect looks for a presidential candidate, Republican Buddy Roemer, whose GOP campaign has struggled badly, would like to be considered.
