U.S. Republican Presidential candidate Marco Rubio, a senator from Florida, is under pressure to win his home state in Tuesday's primary, as losing the key state could well mean his campaign is finished.
The election results on Tuesday were a disaster for Republican elites still clinging to hope that they can stop Donald Trump.
Donald Trump is leading the race to the Republican nomination for the U.S. presidential election, but several other candidates continue to hold on in a show of grit and determination, in a last-ditch effort to try to derail the bombastic billionaire.
It is the kind of campaign he said he would never run. But Senator Marco Rubio, seeing his path to the Republican nomination for the US presidential election growing narrower, has decided that the only way to defeat Mr Donald Trump is to fight like him: rough, dirty and mean.
The next several weeks will be crucial for U.S. Republican presidential candidates as the primary season intensifies with "Super Tuesday" coming next week.
A CNN/ORC national poll released Wednesday shows former Florida Governor Jeb Bush gained popularity among likely Republican voters while Senator Marco Rubio lost momentum, but both trailed Democratic frontrunner Hillary Clinton.
Republican Senator Marco Rubio from the state of Florida announced his decision Monday evening to enter the 2016 U.S. presidential race.
