Look at the campaign he ran and look at what Trump is running. I don't have problems with Trump because of what happened 16 years ago. In addition, I wanted BJP in power more than anything else. As far as I can see, things are going well. India's economy is better and so are its foreign relations.
I'm sure being involved in, and not handling, and being involved in state terrorism in Gujurat (by having rioters attack Muslim houses under order from the administration), matters somewhat, and somewhat more than Trump's idiotic statements. Let us be reminded he was denied entry into the US, until his primeministership.
Also, I'm sure inciting a war against Pakistan is great foreign policy, as well as his disastrous policies in Nepal, which has crippled the country's economy, and has ruined alliances between India and Nepal, all so India can interfere in other countries, well at least foreign relations between India and it's neighboring nations are horrible, as well as country's perceptions of Modi in neighboring asian countries.
