“In her final weeks as secretary of state, Hillary Clinton wrote a private memo to President Obama warning that relations with Russia had hit a low point and the heralded ‘reset’ in relations was over, according to people who saw the document,” the Wall Street Journal reports.

“Mrs. Clinton, if she runs for president, likely will lean heavily on her experience as the nation’s top diplomat.

New York Gov. Andrew Cuomo (D) “is responding to a rebellion from the state’s progressive third party by attempting to push other Democrats away from the Working Families Party,” BuzzFeed reports.

Cuomo political aide and longtime enforcer Joe Percoco has, the sources said, made the request, which is aimed at threatening the party’s ability to get the 50,000 votes for governor in November’s election required for a permanent slot on the statewide ballot.”

Meanwhile, Harry Enten looks at how polling in three-way races is very unpredictable.

“Republican candidates have begun to retreat in recent weeks from their all-out assault on the Affordable Care Act in favor of a more piecemeal approach, suggesting they would preserve some aspects of the law while jettisoning others,” the Washington Post reports.

“The changing tactics signal that the health-care law — while still unpopular with voters overall — may no longer be the lone rallying cry for Republicans seeking to defeat Democrats in this year’s midterm elections.”
