POLL: Who will win the U-23 CONCACAF Championship?

The CONCACAF Olympic Qualifying begins on Thursday evening in Nashville. Canada and El Salvador will raise the tournament's curtain, followed by USA-Cuba in the Group A nightcap.

In this tournament, the two teams that reach the final will earn berths in the Olympic Games this summer in London. But the winner of the final wins the 2012 U-23 CONCACAF Championship.
