South Asian Americans are big US election donors

For presidential hopefuls in the United States, it's still early days in the race for the White House, but the campaign finance machines are all geared up for the show.

Among the big donors and fundraisers are some from the Indian and Pakistani American community. They do not yet have the numbers to wield significant influence as voters in US politics, but they are a highly sought after lot when it comes to campaign cash.

Many of them figure in the elite list of political donors in both congressional and presidential campaigns.

So why do they fund political campaigns, what's in it for them?
