Today's installment of campaign-related news items from across the country.
* In Iowa, a new Monmouth poll shows Hillary Clinton leading Bernie Sanders in the first Democratic nominating contest, 55% to 33%, with Martin O'Malley at 6%. Clinton benefits from a big gender gap: her advantage among Iowa Democratic women is 34 points.
* The latest CNN poll of Iowa Dems points in a similar direction, with Clinton leading Sanders, 54% to 36%.
* In New Hampshire's closely watched U.S. Senate race, PPP now shows incumbent Sen. Kelly Ayotte (R) and Gov. Maggie Hassan (D) tied at 42% each.
* Speaking of Trump, the Republican frontrunner turned his attention to Chris Christie yesterday, arguing that the scandal-plagued New Jersey governor knew about the "Bridgegate" scandal as it unfolded.
* Speaking of Christie, the governor continues to make some inroads in New Hampshire, picking up an endorsement yesterday from state Senate Majority Leader Jeb Bradley (R), a former U.S. congressman.
* The Huffington Post, which announced in July that it would cover Trump coverage through its entertainment section, changed its mind yesterday, and will treat his presidential campaign as a political story.
* And in Louisiana, where Sen. David Vitter (R) is retiring from public office next year, there's likely to be a crowded race to replace him. Rep. John Fleming (R) threw his hat into the ring yesterday.
* Correction: I'd originally linked to a Washington Post piece that referenced the Republican presidential race, but I deleted it because it's out of date.
