When one examines the field of candidates for the Republican Presidential nomination in 2016, Florida Senator Marco Rubio seems, clearly, to be one of the top candidates.
Rubio has many positives, including:
Young, handsome, charismatic
From the ultimate “Swing” state, with the third highest number of electoral votes
An Hispanic (Cuban American)
Representative of a “new generation”
A “fresh face”
Seen by many as the Republican Barack Obama, but also seen as the Republican equivalent of a Bill Clinton or John F. Kennedy in age and charisma
A person with a substantial state government legislative experience, including being Florida House Speaker
But, Rubio also has many negatives, including:
He has to compete against fellow Floridian, former Governor Jeb Bush, his mentor
The Cuban American members of Congress from Florida (Lincoln Diaz Balart and Ileane Ros Lehtinen) support Bush over their fellow Cuban American
Rubio’s support of comprehensive immigration reform, alienating many conservatives, but then backing away from it, alienating other groups, including Latinos who are not Cuban American
Rubio’s being seen as too close to former Miami Congressman David Rivera, who has been seen as involved in corrupt, questionable activities
Rubio being questioned about spending habits while Florida House Speaker, regarding expenditures paid by the state party that were personal expenditures
Rubio being too close to billionaires including Miami’s Norman Braman, and Nevada gambling mogul Sheldon Adelson, and being often in financial difficulties in which Braman has helped him with financial support
Rubio being seen as a Tea Party leader, but trying to separate himself from the extremists of the movement
Rubio seen as not fully understanding foreign policy, where he often seems ignorant of facts and favoring false realities
Rubio seen as not aggressive enough, as compared to rivals, including Texas Senator Ted Cruz, former Arkansas Governor Mike Huckebee, Kentucky Senator Rand Paul, former Pennsylvania Senator Rick Santorum, Wisconsin Governor Scott Walker and Louisiana Governor Bobby Jindal
