America votes in midterm election Today

Americans are heading to the polls today to have their say in who will represent their states and congressional districts. Republicans are bracing for a 'wave' election on Tuesday that could put them in control of both houses of Congress for the last two years of Barack Obama's presidency.

The House of Representatives are more of Republicans, and they expect to enlarge their majority. But the battle royale is in the Senate, where the GOP's 45 seats could become as many as 54 by the time the dust settles.
