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:
* A new Monmouth poll in Iowa shows Scott Walker continuing to lead the Republicans' presidential field with 22% support in the state, followed by Donald Trump with 13%. At this point, no other GOP candidate reaches double digits in Iowa.
* It was quite a scene in Phoenix over the weekend when protesters effectively "shouted two presidential candidates off stage on Saturday at Netroots Nation, demanding policy proposals on racial tensions and police brutality."
* Later in the day, however, Bernie Sanders drew a big crowd of over 11,000 people at a rally in downtown Phoenix.
* Chris Christie's super PAC has made a $1.1 million ad buy in New Hampshire, focusing on the New Jersey governor's opposition to international nuclear diplomacy with Iran. In the spot, Christie claims to be "the only candidate who has actually been responsible for fighting terrorism."
* Jeb Bush, probably taking a subtle shot at Marco Rubio this morning, mocked members of Congress "who sometimes seem to regard attendance and voting as something optional." Rubio has the worst attendance record of any member of the U.S. Senate.
* Hillary Clinton's campaign has reserved "nearly $8 million in television time for a fall advertising blitz" in Iowa and New Hampshire, with commercials set to air "as early as the first week of November."
* The race for the Republicans' U.S. Senate nomination in Florida is getting quite crowded, with Rep. David Jolly (R-Fla.) joining the growing primary field this morning.
* And speaking of the Sunshine State, with Rep. Patrick Murphy (D-Fla.) running for the Senate, what will the DCCC do to keep the seat? Party officials are focused on multimillionaire Randy Perkins, who hasn't announced his plans, but who seems interested in the race.
