This will be detrimental to the very same Hindutva he subscribes to. Votes will be divided between the BJP and his candidates. Even if he considers BJP to be not a "staunch" Hindutva, it's atleast some Hindutva that other parties don't adhere to. So it will hurt both BJP and his party which might benefit SP, BSP and others. This factionalism is detrimental to nationalism and seems to be individually motivated more than anything.
