It will b Mr. Ansari if Congress is in power after 5 years...As after remaining VP for five years his name will be proposed for the president(In case he wins VP election)....if BJP is in power then it will be Najma Haptullah(And if she wins VP election then also her name will b proposed for next presidential election....No serving VP has ever lost the election except...Bhaiov Singh Sekhavat...So these are the likely choices...So forget about many great names buddy!
