No successor will be formally anointed before end-2027; Modi keeps Amit Shah, Yogi Adityanath and Fadnavis in rivalry rather than designate an heir, because a named deputy would trigger lame-duck erosion.
Strongest counter — An RSS centenary push or a health event could force early transition planning. The 'deliberate rivalry' motive is interpretive mind-reading, though the prediction itself is cleanly falsifiable. Defended: Modi has never named a successor and formal deputy-PM naming is historically rare in the BJP; base rate strongly favors the call.
Wrong if — Any formal deputy-PM designation or public heir-apparent naming before 31 Dec 2027.
