David J. Tubiolo (born September 10, 1987) is a Democratic politician from Yonkers, New York.

[4] Tubiolo in February 2020, switched from the Republican to Democratic Party on the Westchester County Board of Legislators.

[13][14][15] Tubiolo laid some blame to President Donald Trump stating, “I cannot blame Donald Trump alone for all of the problems this country faces, but his actions have created unprecedented divisiness and an atmosphere of intolerance that must change, I will not sit by idly and watch everything I stand for erode away while immoral policies like child separation are handed down from Washington.

That means addressing crushing student loan debt, making corporations pay their fair share, stronger gun laws and comprehensive policies to protect workers from automation, that means paid parental leave for all employees.

That means everyone has the opportunity to pursue the American dream, regardless of where they were born.”[16] After the switch, Doug Colety, chairman of the county Republicans, stated: “It’s a betrayal of the voters who elected him in past elections,” Colety said in a phone interview.
