OkPK is a steroid for campaign and insurance to win in polling for TDP.. In Hindsight after Term finishes it may look as unnecessary but the fear from loosing is transparent in CBN and TDP fans during prepoll.
Raithu runa maafi kudaradu ani chala mandi antunnaru kaani I don't think it is a big issue.
Even if there is 1 Lakh crores of debt Government can possibly do the following:
1. Tranfer the debt to state governement and clear it over time. For this they only need to be able to pay the interest payments upfront.
2. Or let the farmers off the hook by signing agreements with banks to pay off debt in 5-10 deferred payments. Then they will only need 10K crores per year.
