In my opinion, you don't need to be US citizen to be interested in US politics.  Yes, you don't have to be interested, but if you are, it just means that you like being aware of what is going around you.  Plus, like it or not, who the next occupant of White House matters to not just the US but also to the world.

"Kaag lai bel pakyo, harsha na bismaath" bhanney comment chai is probably more appropriate for those who are not interested (nothing wrong with that) or plain old ignorant (something is wrong with that).

I for one will be glued to TV from 6:30pm onwards on Nov. 4th.  Chances are, we will know Obama is the new president by 8:30pm.
