US Republicans nominate Romney as presidential candidate

TAMPA, Fla. - Republicans formally nominated Mitt Romney as their presidential candidate on Tuesday to face Democratic President Barack Obama in the Nov. 6 election.
By voice vote in a raucous arena, delegates to the Republican National Convention united behind the former Massachusetts governor, who this year outlasted a series of conservative challengers to come out on top.
Romney, 65, is in a close fight with Obama with 70 days to go until the election and Republicans hope he will gain some much-needed momentum from the Tampa convention this week.
