CNSNews.com) – John Brennan, who served as CIA director under President Obama, is a fierce critic of President Trump. Among other recent criticisms, Brennan said Trump has been “duped” by the “masterful” North Korean dictator Kim Jong-un.

Speaking to Fox News on Monday night, Trump adviser Kellyanne Conway called Brennan’s comment “very irresponsible” and “irrational.” She said the constant harping by people like Brennan actually is boosting the president’s popularity:

And I would say that Mr. Brennan and others who started in the administration before ours should remember that old saying that politics stops at the water’s edge. These are decidedly nonpartisan issues looking for bipartisan support. And I would hope that someone who was involved in the previous administration could at least see the prospects, the prospect, of opening up relations there and denuclearizing the Korean peninsula.

North Korea has already, in the gift of this president’s leadership, released those three Americans back here, and even then people couldn’t just applaud it and say isn’t that a wonderful day for those three men to be free. They had to make it partisan and political, and I think that’s partly why the president’s poll numbers are improving because people are so tired of the reflexive invective and the inability and the irrationality of not being able to say today was a good day for America.

Finally on the point of North Korea, this president has made clear again and again that things are looking very promising. The summit is set for June 12th, but at the same time, the president said he will see what happens — that these conditions need to be met. But so far, we like the fact that they’re suspending their tests. They’re releasing Americans, and this president feels that we are at a very good place moving forward to June 12th.

Meanwhile, former San Francisco Mayor Willie Brown, a Democrat, is warning his party to stop bashing President Trump.

In a May 12 column in the San Francisco Chronicle, Brown wrote:

It’s time for the Democrats to stop bashing President Trump.

It’s not going to be easy, given his policies and personality. It might even mean checking into a 12-step program. But setting a winning agenda is like maneuvering an aircraft carrier. It takes time to change course. And if they want to be on target for the November midterm elections, the Democrats need to start changing course now.

President Trump’s policies remain popular with many Americans, which means Democrats need to find a campaign strategy beyond just bashing him. Trump is more popular than Dems want to admit.

Like it or not, a significant number of Americans are actually happy these days. They are making money. They feel safe, and they agree with with the president’s protectionist trade policies, his call for more American jobs, even his immigration stance. The jobs growth reports, the North Korea summit and the steady economy are beating out the Stormy Daniels scandal and the Robert Mueller investigation in Middle America, hands down. So you are not going to win back the House by making it all about him.

Rather than stoking the base by attacking Trump, Democrats need to come up with a platform that addresses the average voters’ hopes and concerns. Not just the needs of underdogs or whatever cause happens to be the media flavor of the week.
