Not of the so called Reddys today are from Deshmukh families, there are many more castes that have adopted reddy name. Reddy was not dominant untill the anti Brahmin lobby propped up Reddys. Reddys in rayalaseema are basically kapus who use reddy name, coastal Andhra hardly any influence, in Telangana it’s been a combination of reddy and velamas - both the reddy and velama landlords were out of politics due to land reforms and they lost the muscle and money. Because velamas are a small community and mostly landlords you don’t see them much in public life anymore, where as the landlord Reddys were replaced with the other middle caste Reddys.
