House Republicans are ramping up their campaign efforts with a new ad blitz that links Democrats to New York City Mayor-elect Zohran Mamdani, who has been criticized for his democratic socialist views. This strategy aims to sway voters in key battleground districts by painting Mamdani's affiliation as a liability for Democrats, highlighting the ongoing political divide. The National Republican Congressional Committee is investing heavily in this campaign, which underscores the significance of the upcoming elections and the fierce competition for control of Congress.
