Not only has President Donald Trump upended national politics, he's had a profound impact in New York, with the mayor, governor and other elected officials each taking a different tack in countering the Trump agenda. NY1's Bobby Cuza filed the following report.

When Mayor Bill de Blasio held an event Friday trumpeting a property tax break for seniors, the choice of location was telling. 

"I cannot be at Trump Village and not make a brief statement," he said.

The mayor wasted no time at the top of his remarks contrasting his policies with the president's.

"President Trump's tax plan was written by billionaires for billionaires," de Blasio said. He added, "Talk about night and day. You are seeing the polar opposite right here in the city of New York."

It's typical of the mayor's approach of taking Trump head-on. He's appeared at protests including a Muslim solidarity rally, held numerous press conferences solely to denounce White House policies and generally positioned himself as the anti-Trump, fighting for the city's interests.

He has said things like, "This is a charade. They’re not actually serious about driving down crime," and "What is Sean Spicer's problem, and what is President Trump's problem?" 

It's unquestionably good politics for the mayor, who just Monday used Trump in a fundraising email. Policy-wise, he's argued New Yorkers will suffer under Trump's agenda, from health care to immigration to proposed federal funding cuts that have thrown New York’s budget into limbo, both city and state.

Governor Cuomo has taken a less direct approach, criticizing policy like Obamacare repeal.

"You're not going to undo the progress that President Obama made," Cuomo said 

But he has not gotten personal, perhaps wary of provoking Trump, with whom he's enjoyed a more cordial relationship.

As for Senate Minority Leader Chuck Schumer, he's not shied away from criticism, like in grading Trump's first 100 days.

"It’s an F," Schumer said. "He has not kept his promises."

But he has not attacked as aggressively as the mayor.

Trump has shown little sign of changing course, at least when it comes to policies perceived as hostile to New York;s interests. Which means if he;s been a gift politically to Mayor de Blasio over the past 100 days, it's a gift likely to keep on giving throughout the rest of this mayoral election year and beyond.
