Are poker winnings considered normal income when it comes to taxes?

[FlashFunk]

For example. If I have only 2 sources of income, my job and the money I make from poker. Suppose I make 8000 a year at my job and 2000 a year at poker. Is this the same as me making 10000 a year at my job without playing any poker?

In other words would I still be in the lowest income bracket and would my poker winnings be taxed on that brackets rate (i think its 10% for the lowest income bracket)?
