Democrats congratulated Zohran Mamdani on his historic win, while Republicans issued warnings.
Long Island officials kept their distance, as Republicans, including House Speaker Mike Johnson and New York State GOP Chair Ed Cox, claimed Mamdani's victory solidifies the Democrats' transformation to a big-government, socialist party.
They asserted Democrats will face the negative consequences of that in congressional and other elections next year.
House Minority Leader Hakeem Jeffries dismissed these Republican depictions.
Mamdani's win sparks divided reactions from D.C. pols.
