Ideologies are not as watertight as you seem to think/wish/expect.

Pinarayi and his party are clearly social democratic because they fight elections, they borrow money from the market, they even have schemes to encourage private entrepreneurship. Going by your logic of how mutually exclusive and strict the motivation of ideology in actions must be, US should have refused a medical tourist entry owing to his ideological leaning. Why would otherwise Mayo accept the money. Why did the liberal west go from Smith to Keynes if ideologies were that watertight.

Public debt doesn't make the state debt ridden until the percentage of it wrt GSDP cross an alarming rate. At 37% last year, it's as normal as it usually is.
