The Note: The Marco Rubio Moment

— -- --ANALYSIS -- ABC's RICK KLEIN: Get ready for a Marco moment. A new Quinnipiac poll is the first national poll to have Sen. Marco Rubio as the frontrunner, garnering 15 percent of the GOP vote, to Jeb Bush's 13 and Scott Walker's 11. It's an announcement bump, surely, but a well-timed one: Rubio is just not making the case to donors and activists that he belongs in the top tier of contenders, the ones for whom big wallets should rightfully open. This poll seems likely to put him in the big leagues. What might keep him there is his remarkable and stable strength in the poll among a range of subsets of the Republican electorate. He's drawing between 13 and 16 percent of voters among evangelicals, tea partiers, "very" and "somewhat" conservatives, and moderates, in addition to both men and women. Early polls are like scoring first in a baseball slugfest, of course -- not that anyone doesn't like an early lead. "The early polls are going to bounce all over the place, so we'll let others analyze them while we stay focused on our positive conservative vision for a new American Century," Rubio spokesman Alex Conant told ABC.

--CLINTON CASH DAY: ABC's CECILIA VEGA reported for "Good Morning America" on today's flurry of stories about allegations in the new "Clinton Cash" book and how her campaign is reacting. The Clinton campaign's national press secretary Brian Fallon has been circulating a memo meant to arm supporters and allies with ammunition to fight back against the allegations in the forthcoming book by Peter Schweizer. "It goes without saying that the Clintons are rightfully proud of the critical work done by the Clinton Foundation," Fallon writes in the memo, obtained by ABC News. "It is a world-class philanthropy that has helped millions of people around the world tackle issues from HIV/AIDS to children's health to climate change. It is sad, but not surprising, that their philanthropic work has become the subject of false, right-wing attack." WATCH: http://abcn.ws/1OhaGG5

--BOEHNER ON BENGHAZI AND HILLARY: With the Benghazi Select Committee's investigation dragging on into the presidential campaign, House Speaker John Boehner criticized the Obama administration and Democratic presidential candidate Hillary Clinton for a lack of cooperation in the House's investigation into the deadly Benghazi terrorist attacks in 2012. Although Chairman Trey Gowdy has signaled that his committee's report will not be issued until sometime next year, Boehner said the committee "is doing fine work" but has "a lot more work to do," ABC's JOHN PARKINSON reports. "They could clean this up a whole lot quicker if the administration and...former Secretary Clinton were in a position to actually cooperate with the committee and turn over the kind of information that we've been seeking for some time, but the administration has made it virtually impossible to get to the facts surrounding Benghazi," Boehner, R-Ohio, told reporters yesterday.
