Congress leader Priyanka Gandhi Vadra waved at people and took scores of selfies as she went on a roadshow through the bustling streets of Ghaziabad near Delhi, where her party's candidate is taking on the BJP's VK Singh, a union minister and former army chief, in the national election starting next week. "Think carefully before voting, those in power have forgotten you gave them power," she said, addressing a crowd from the sunroof of an SUV.
