The main candidates for the Democratic and Republican Party presidential nominations are jetting across America in the final day of campaigning before Super Tuesday -- the biggest ever day of voting in a nomination race.

On the Democratic side, the latest opinion polls indicate a dead heat between Senators Hillary Clinton and Barack Obama.
But polls on the Republican race put Senator John McCain ahead of his main challenger, Mitt Romney.
