This Week in Politics: The Mayor Makes it Official

Mayor Bill de Blasio delivers remarks at Rev. Al Sharpton's Nation Action Network 2019 Convention at the Sheraton New York Times Square Hotel in Manhattan on Wednesday, April 3, 2016.

New York City Mayor Bill de Blasio announced he was joining a field of more than twenty Democrats for the presidential nomination this week. And we've been hearing from plenty of New Yorkers who had lots to say about his candidacy. One of them - The President - was kind enough to Tweet that de Blasio was the "worst mayor" in the history of the city.

But what does a national audience think? What about Iowa, South Carolina and New Hampshire? Amy Walter joins us for a national perspective on the mayor. She's National Editor of the Cook Political Report and host of Politics with Amy Walter, heard every Friday on The Takeaway on WNYC.
