--ANALYSIS -- ABC's RICK KLEIN: Does Jeb Bush need Donald Trump to get his groove back? That might depend on what groove he falls into, since he's out carving a new one that adjusts to the new realities of the race. It's hard to imagine that Bush ever saw himself as likely to attack another front-running candidate for being insufficiently conservative, as he unloaded on Trump on taxes, healthcare, abortion, and even past party affiliation on Thursday. It was more fiery than Bush has been in recent weeks, though his comments are admittedly mild compared to things Trump has been saying about Bush since before the beginning of the campaign (May: "Not even a smart person"; August: "Very low energy"). Bush would surely rather not have a debate over the term "anchor babies," where he's coming under fire for using the same term as Trump, while holding the opposite position. But perhaps the most impactful statement from Bush land on Trump comes not from the candidate but from the chief strategist of his super PAC: "Trump is, frankly, other people's problem," Mike Murphy told The Washington Post.

NYC TRIES TO FIND A WAY TO CANCEL CONTRACTS WITH TRUMP. Mayor de Blasio's office has concluded that New York City cannot terminate any contracts with Donald Trump. "We reviewed the city's existing contracts with Donald Trump and found no legal way to cancel these contracts. In the future, however, the mayor said he would not go out of his way to do any business with Mr. Trump," said Monica Klein, a mayoral spokeswoman. Trump has contracts with the city that include two ice skating rinks and the carousel in Central Park and a golf course in the Bronx. The mayor ordered the review of contracts after Trump mocked Sen. John McCain's status as a war hero, according to ABC's AARON KATERSKY.
JEB BUSH LEANING ON FAMILY: THE FUNDRAISER WITH BUSH 41 AND 43. On October 25-26, there will be a huge donor summit in Houston, TX featuring much of the Bush family, notably George H.W. and George W. who will be headliners. Barbara Bush will also be in attendance. The event has been dubbed "Q3 Mission 2015: Jeb Celebration" and is hosted directly by the campaign. To garner an invitation, potential attendees must have raised at least $50,000 for the campaign. This comes amidst all the Trump-mania, the back and forth between the current frontrunner and the former front-runner... Bush struggling to regain his footing in a kind of race he never saw coming. Obviously, this fundraiser could be a huge cash-cow for Bush as he's now leaning on his father and brother's wealthy network to pump some cash [and life] into this floundering campaign. Of course- on the other side, as Jeb! tries to distinguish himself from his brother and those unpopular policies, this could hurt that effort, bringing into view those inextricable links between Jeb and his family's legacy, ABC's CANDACE SMITH writes.

"TIME FOR REGIME CHANGE IN IRAN," a Jerusalem Post Op-Ed by GOP presidential candidate Mike Huckabee. "This week as I returned to Israel to meet with Prime Minister Benjamin Netanyahu and other key Israeli leaders, it's clear that Iran is ripe for another revolution. This time, with US support, Iran's democratic opposition could topple the Islamic Republic and put an end to the ayatollahs' threats to 'wipe Israel off the map' and bring 'death to America.' The Iranian regime lost the confidence and support of its own people long ago. During the Green Revolution of 2009, the Islamic Republic faced the greatest threat of its 30-year existence at the hands of its own people. ... I would announce on my first day as president that the new policy of the United States is to support freedom in Tehran. I would double-down against Iran with tougher sanctions. Officials within the Iranian government, clerical establishment and military would face a clear choice: They can stay on a sinking ship, or abandon a regime that has outlived its shelf life." http://bit.ly/1JtH1Y7
