The Note: GOP's hopes and fears in Trump's hands GOP's hopes and fears lie in Trump's hands.

WASHINGTON, D.C. -- The TAKE with Rick Klein

Former President Barack Obama over the weekend called it a “push and pull” – a contrast “between those who promote the politics of hope and those who exploit the politics of fear.”

The stage is set for two presidents to do battle over the next eight weeks, with the GOP’s hopes and fears wrapped up in the sway and conduct of President Donald Trump.

Republicans hope that concerns about Trump’s fitness for office and penchant for drama won’t subsume their messaging. They fear that there’s little to nothing that can be done about that.

They hope that the walls of Robert Mueller’s investigation don’t squeeze the president to the point of further lashing out – or worse. They fear that wrinkles like those added by George Papadopoulos are inevitable.

As for Obama, his voice gets elevated as the primary season winds to a close. Democrats recall what the politics of hope can bring, but fear the memories of when it has fallen short.

The RUNDOWN with MaryAlice Parks

The White House is benefitting from the mystery “who-dunnit” over last week’s anonymous op-ed, let alone perhaps from outing the culprit.

By focusing the attention on who exactly penned that anonymous op-ed in the New York Times, the White House can try to paint a picture of a villain, a singular bad guy.

In fact, if you stop to re-examine the content of the op-ed — written by a senior administration official who accuses the president of amorality and claims people within the administration are in essence saving the country from the president himself — you’ll find themes that are both disturbing and widely repeated.

What’s makes the article especially powerful is that the assertions line up with the recent book put out by veteran journalist Bob Woodward, and statements from outgoing staff.

As ABC News’ Chief White House correspondent Jon Karl said on “This Week” Sunday, “From the first weeks of the Trump administration, I have had top people on his team, including people very much with the program generally, tell me, ‘You think it’s crazy. You should see the stuff we stop from happening.”’

But by making it about the search for the author, the president is deflecting from the prose.

The TIP with Christopher Donato

New York’s insurgent Democratic gubernatorial candidate Cynthia Nixon is calling a flier sent out against her “disgusting” and “deeply offensive.”

The flier, paid for by the New York Democratic Committee, insinuated “inexperienced Cynthia Nixon” is anti-Semitic and won’t stand strong for Jewish communities. Gov. Andrew Cuomo said on Sunday that he “didn’t know about the mailer” and that the language was “inappropriate.” The New York State Democratic Committee on Sunday called the mailer “wrong and inappropriate” and the committee’s executive director, Geoff Berman, said that party “will work with the Nixon campaign to send out a mailing of their choosing to the same universe of people.”

While greeting voters in Manhattan on Sunday evening, Nixon told reporters that the mailer was full of “outright lies” and called for the party to fire those individuals who were “involved in concocting this flyer, executing it, [and] signing off on it.”

The mailer was the latest setback for Cuomo this weekend. On Friday, the Tappan Zee Bridge had become “destabilized,” delaying the opening of the new Mario Cuomo Bridge. Cuomo had attended the new bridge’s ribbon cutting ceremony hours earlier.

The primary for New York governor will be held this Thursday, Sept. 13.
