File Image Jaipur: Even as the Congress is putting all its might into winning all four of the assembly by-polls slated to be held next month, the names of Chief Minister Ashok Gehlot and Assembly Speaker Dr CP Joshi's sons have cropped up as possible candidates. Party insiders say that Gehlotâs son Vaibhavâs name is being considered for the Rajsamand seat while Joshiâs son Himanshu could fight for the Sahada seat in Bhilwara district. Vaibhav has visited Rajsamand four times in the last month and the Congress sees a good chance of winning the seat. In the recent urban local body election, the Congress had wrested the municipal council from the BJP and formed its board after almost 30 years.
