Don't be too sure that he has no numbers. A clue to the numbers is to see where smaller parties are gravitating to.
So you see the SP, JDS, NC, ILD, MDMK, TMC etc all gravitating to the Congress.
Left is left with only TDP.
NDA has seen not only desertions (TMC, ILD, NC, MDMK etc) but allies expressing ambivalent sand like Shiv Sena and Akali Dal who are most likely to abstain
The direction where parties gravitate indicate where people's support lies.
