Before I say anything I would like to disclose my knowledge of political affairs in India. I had lot of assumptions and predictions for this just concluded elections, and none of them came true. So I am not going to talk politics and waste time. But this election season reminded me of a funny incident when I was a student in Arizona State University (ASU) in 2004.
As a thumb rule, I discuss politics only with close friends. So my flat mates in Phoenix had no idea about my political likes and dislikes. So on the day when BJP lost the elections, one of my flat mates – who used to hate George Bush and an active supporter of Democrats – saw me in that morning, and said, "What John, people have done this" in a disappointed tone.
He saw no contradiction whatsoever in supporting democrats in US and at the same time supporting BJP in India. It was after that I started noticing Indian students in US, and people who got their jobs in US recently, most of them exhibited this kind of duality.
Later, I was discussing this with a sociologist professor (who teaches in a US university), he told me these students over time when they acquire wealth, they might shift their allegiance to Republicans. I have no data to prove my assertion of duality of newly arrived Indians in US or what my sociologist friend was saying.
Probably ideology doesn't matter, support any party which is favourable to them.
