Sitting MP Datta Meghe's son Sagar and former Rajasthan Governor Prabha Rau's daughter Charulata Tokas are in the fray for the party ticket.
Wardha recently figured in the list of primaries at the expense of Yavatmal Lok Sabha constituency which was dropped along with Aurangabad, apparently due to factionalism in local units.
According to sources, senior Meghe is not keen to contest elections due to his age and wants to hand over the reins to Sagar, a former BJP MLC who had joined Congress under late Chief Minister Vilasrao Deshmukh.
Both the aspirants had organised a couple of rallies for Congress in the district.
