Today's installment of campaign-related news items from across the country.
* In Iowa, the new Fox News poll shows Hillary Clinton leading Bernie Sanders by six points, 48% to 42%. That's much closer than the 14-point advantage Clinton enjoyed in a Fox poll from early December.
* In New Hampshire, the latest Boston Herald poll shows Sanders building on his lead over Clinton among Granite State Democrats, 55% to 39%.
* Clinton is in better shape in national Democratic polling. A new CNN poll shows her ahead 52% to 38%, while Fox has Clinton leading 49% to 37%.
* At a forum last night, Sanders emphasized tax increases as part of his campaign platform. "We will raise taxes, yes we will," Sanders said in a quote that will end up in an attack ad if the senator wins the nomination.
* An interesting tidbit on the Democratic data: pollsters that rely on random-digit dialing tend to show Bernie Sanders faring well; pollsters that rely on voter-registration files tend to show Hillary Clinton in the lead.
* In Kentucky, Lexington Mayor Jim Gray (D) kicked off his Senate campaign this morning, throwing his hat into the ring to take on Sen. Rand Paul (R) in November. Paul, you'll recall, is also a struggling presidential candidate, who hasn't spent much time in his adopted home state lately.
* Ted Cruz has an effective new ad targeting Donald Trump, taking aim at the frontrunner's "New York values," which includes the time Trump described himself as pro-choice.
* The editorial board of the Boston Globe, which has a sizable audience in New Hampshire, has endorsed Ohio Gov. John Kasich in the Republican primary.
* Trump may not have any Senate endorsements, but Stephen Miller, a top aide to Sen. Jeff Sessions (R) of Alabama, is joining Trump's campaign as a senior policy adviser.
* And in the former-candidate club, George Pataki this morning threw his support to Marco Rubio, while Lindsey Graham wrote an op-ed over the weekend touting Jeb Bush.
