U.S. Senator Marco Rubio, the youngest Republican candidate to fight for the Republican Party (GOP) nomination, could be the party's main hope to beat Democrat rival Hillary Clinton, experts said.
Indeed, there has been talk in U.S. media recently that donors start to shift their funding away from early GOP favorite Jeb Bush, former Florida governor and brother and son of two former presidents. While Bush just a few months ago was considered a shoo-in for the nomination, he has been trailing in the polls and has not made an impressive show in any of the four GOP debates.
Although polls have Rubio trailing front-runners Donald Trump and Ben Carson, Rubio has fared well in recent GOP debates, especially the debate earlier this week that saw more than a dozen candidates in a verbal joust to gain the nomination.
Republican strategist Ford O'Connell told Xinhua that at least over the last several debates, Rubio has been "the most substantive while also looking presidential."
Indeed, until votes are cast, it will be difficult to forecast who will get the most support from voters, although Rubio is certainly attracting attention away from Jeb Bush, O'Connell said.
