Speculation over Priyanka Gandhi Vadra's electoral debut had reached a crescendo ahead of the Lok Sabha polls, only to be completely deflated when she decided against contesting. The buzz has started gathering steam again, however, with sources telling NDTV on Thursday that the Congress leader may be the Congress candidate for the bypoll from the Wayanad Lok Sabha constituency if Rahul Gandhi vacates the seat. Mr Gandhi, who had won the Lok Sabha polls - with considerable margins - from both the Raebareli and Wayanad constituencies, also fanned the flames of a possible debut by his sister when he said on Tuesday that Prime Minister Narendra Modi would have lost "by two-three lakh votes" if his sister had fought against him in Varanasi.
