Rubio who is a young Cuban American, is a conservative and considered in the forefront of the Tea Party's assault on the US Congress.

Addressing his supporters after his win, Marco Rubio said:
"There was a moment earlier in this campaign where I didn't know how I was going to raise the money to be competitive and I'll never forget the next morning my children showed up and they had collected their allowance which was largely quarters and single dollar bills and handed it to me - I didn't tell them that, they overheard me - and it was in that moment I was reminded about what this race and election was really all about. It was not about any of our individual ambitions, but it was about the future.

"Our Nation is heading in a wrong direction,and both parties are to blame. And what Americans are looking for desperately are people who will go to Washington DC and stand up to this agenda that is taking us in the wrong direction and offer a clear and genuine alternative."

While Rubio won through, another Tea Party darling Christine O'Donnell fell short. Despite her quirky personality, a series of financial woes and her idiosyncratic views on religion failed to convince middle of the road voters in Delaware to back her.
