NEW DELHI — Priyanka Gandhi on Tuesday said she was hurt by the political attacks on her husband and family and vowed to fight back detractors with increased determination. Referring to attacks on Robert Vadra, Priyanka said, “Lot of harsh words are used for my family, my husband. They are trying to humiliate my family. It’s sad. But I had learned from Indira ji on how to bear all this,” referencing her grandmother and former prime minister, to whom she bears a striking resemblance. “Attempt is being made to malign my husband,” she said, addressing a gathering in Raebareli. “The more they try to humiliate me, the stronger will be my response, Priyanka said, urging people to vote for Sonia Gandhi. “Don’t vote for Sonia Gandhi, vote for your children and a country where people love each other,” Priyanka said, adding, “My mother wasn’t born here, but you’ll accepted her. That’s the beauty of this country.” Priyanka reminded voters of the special relation that Sonia shared with them. The opposition’s allegations that Vadra was given sweetheart land deals in Haryana have been an embarrassment for the Congress party, which governs the state. The party is headed by Priyanka’s mother, Sonia; its national campaign is being fronted by Rahul Gandhi, who is a year older and is grappling with forecasts of a dismal performance. Modi, who in recent speeches, has dared the Gandhis to furnish an explanation for what he describes as Vadra’s sensational fortune, accrued in recent years. Priyanka, 42, is not running for Parliament, but is managing the campaigns for her mother and brother in their constituencies in Uttar Pradesh. In October, the Supreme Court rejected any investigation into Vadra’s land deals, saying that a person “can’t be called a sinner merely because he is linked to a politician.”
