U.S. Senator Dianne Feinstein shocks an audience in San Francisco saying Trump could be a good president.

Sen. Dianne Feinstein may be San Francisco's favorite politician, but she quickly learned Tuesday evening that even a wildly popular ex-mayor can get into trouble if she tries to say something nice about President Trump.

Feinstein received a standing ovation from the 850 people at the sold-out Herbst Theater when she walked onto the stage for an hour-long "conversation" with former East Bay Rep. Ellen Tauscher. But near the end of the political lovefest, the senator shocked the crowd when she declined to say that Trump should be impeached, and warned the audience that they should expect to deal with the developer-turned politician for all four years of his term.

"The question is whether he can learn and change," Feinstein told the crowd at the Commonwealth Club event. "If so, I believe he can be a good president."

That sort of talk is never heard in Democratic circles, where California Congress members already are talking about what they see as the need to impeach Trump or remove him from office via the 25th Amendment.

The crowd reacted with stunned silence, broken only with scattered "No's" and a few hisses and some nervous laughter.

But Feinstein didn't back away, reacting to a question about why Democrats aren't being more out front in attacking Trump by reminding people that not only is Trump president, but he's also only been in office for eight months.

"We'll have to see if he can forget himself enough and have the type of empathy and direction the country needs," she said.

If he doesn't, she added, "there are things that can be done."


Comment: How magnanimous of her; if Trump 'behaves' (i.e., if he doesn't try to break out of the constraints he has been put in), then they won't impeach or otherwise 'off' him.


Feinstein argued that a strategy of all attack, all the time, wasn't going to make it easier for her or any other Democrat to accomplish anything in Washington.

"I have to work with people and a punch in the nose is not going to do it," she said.

While Feinstein didn't change the jeers to cheers, at least some of the crowd saw, albeit reluctantly, where she was coming from.

"I thinks she has to continue to be hopeful... if she's going to be working with people," said Pat Belotti of San Francisco.

If Feinstein is going to work in a bipartisan way, she needs to think things will get better, said Sarah Small of Burlingame, "even if she might not be right."

Even Tauscher, who pointedly suggested that "it's a little late by my watch," for Republican politicians to publicly repudiate many of Trump's statements and proposals, admitted that she would likely be more circumspect if she was still in Congress.

But during her time on stage, Feinstein also reminded the crowd why she often causes California's progressives to grind their teeth.

When asked what she would do about Trump's plan to renegotiate the North American Free Trade Agreement, Feinstein reminded the crowd that she had voted against NAFTA in 1993, arguing that it would take manufacturing jobs from California and move them to Mexico.

"I believe it should be renegotiated," she said, making it more fair and more up to date.

But Feinstein also showed she was far from Trump's forever friend, slamming the president's slow and seemingly reluctant response to the racism of the march in Charlottesville, Va., earlier this month.

"The president shouldn't have tried to placate both sides," she said to loud applause. "You cannot placate American Nazis. You cannot placate white supremacists."


Comment: You cannot placate radical leftists/anarchists either, Ms. Feinstein.


Feinstein also blasted his pardon of former Arizona Sheriff Joe Arpaio last week, saying that the decision was a signal to police across the country that racial profiling is OK.

"It was a stupid thing to do," the senator said.

But the 84-year-old Feinstein was far less straightforward when Tauscher asked her, in a roundabout way, whether she would run for a new six-year term next year.

"Next question," the senator replied.
