Today's installment of campaign-related news items from across the country.
* As Democratic presidential hopefuls fight for positioning in Iowa, the editorial board of the Quad City Times endorsed Amy Klobuchar's candidacy over the weekend. Around this time four years ago, the same newspaper endorsed Bernie Sanders.
* Speaking of newspaper endorsements, the editorial board of the New York Times caused a bit of a stir overnight, publishing an editorial endorsing both Klobuchar and Elizabeth Warren.
* Bernie Sanders, meanwhile, picked up the backing of Rep. Pramila Jayapal (D-Wash.), who has also agreed to serve as the national health policy chair for the Vermont senator's campaign. Sanders now has seven endorsements from sitting U.S. House members.
* With just two weeks remaining before the Iowa caucuses, a Focus on Rural America poll found Joe Biden leading the pack with 24%, followed by Elizabeth Warren at 18%, and Pete Buttigieg at 16 percent. Bernie Sanders was right behind them in the poll with 14%, and Amy Klobuchar also reached double digits, showing 11% support.
* The DNC has unveiled the participation thresholds for the next presidential primary debate, scheduled for Feb. 3 in New Hampshire. To qualify, candidates will need donations from at least 225,000 unique donors, as well two polls with 7% support in early contests or four polls with 5% support in early contests or national surveys. As things stand, each of the six candidates who met in last week's poll have already qualified to be on the stage in the next debate.
* And Michael Bloomberg's aggressive advertising campaign has sparked an unexpected problem: as demand for television airtime grows, and supply dwindles, Politico reports that the former mayor's blitz is "causing stations to raise ad prices at a time of high demand."
