Who are the Republicans front runners for 2028?

How he is viewed nationally

The numbers are better than you might expect for someone in the current administration. A Rasmussen survey finds 47% of likely voters view Rubio favorably, up from 45% the year before, with 25% holding a "very favorable" impression. That is a meaningful trend in the right direction. The Harvard CAPS/HarrisX poll tells a similar story: only Robert F. Kennedy Jr. and Rubio post positive net favorability among a dozen prominent American political figures tested. In a field where almost every major name is underwater, that alone is a structural advantage.

Pew Research, which surveyed a broader adult population rather than likely voters, is less rosy: Rubio is viewed more unfavorably (44%) than favorably (34%) in that sample. The gap between the two polls reflects who is being asked. Likely voters lean more Republican; all adults skew the other way. The real number for a general election is somewhere in between, and competitive.

The biggest positive signal for 2028 is how he compares to his rivals. CNN analyst Harry Enten noted that Rubio's net approval is -6 points, which is far better than Vance at -15, Pete Hegseth at -21, and Kash Patel at -26. Rubio might have the best argument that he would play better in a general election than any of the other Republicans tied to Trump.

The Cuba question

Cuba is Rubio's deepest conviction, and it shows. As Secretary of State, he is waging what Axios describes as an unprecedented economic war on Cuba, rolling out waves of new sanctions across Cuba's tourism, energy, trade, and security sectors as part of a maximum pressure campaign aimed at overthrowing the island's government.

In a Republican primary, this is almost pure upside. Cuban-American voters in Florida, a must-win state, have been the most reliably anti-Castro constituency in American politics for 60 years. Rubio's family story, his parents left Cuba before Fidel Castro took power, makes the policy feel personal rather than political.

In a general election, it gets more complicated. Democratic members of Congress who visited Havana reported that the fuel embargo and escalating sanctions are strangling ordinary Cubans, with some calling conditions there a "silent Gaza." That framing, fair or not, gives opponents a ready-made narrative about collective punishment. There is also a practical risk: a collapse in Cuba could spark a new migration crisis at exactly the moment the administration has staked its identity on border control. Rubio would have to answer for that.

The honest read is that Cuba policy fires up his base and probably does not cost him many Republican votes. But it hands Democrats a line of attack in swing states that have nothing like Florida's Cuban-American community.

Where he has the edge over Vance

Three clear advantages.

First, the favorability gap shown above. Vance is considerably more polarizing nationally, and a candidate who is already at -15 net approval before a general campaign even starts is fighting uphill.

Second, age and crossover appeal. Rubio leads Vance among Republican primary voters over 50, 41% to 35%, the older, higher-turnout segment of the base. And his profile as a Cuban-American from a swing state gives him a plausible path to Latino voters that Vance simply does not have.

Third, the Secretary of State role itself. Running foreign policy for the world's most powerful country is a credentialing machine. Every diplomatic moment, every negotiation, every crisis managed is a résumé line. Vance, as Vice President, is more visible but also more tethered to every unpopular decision the administration makes. Rubio has more room to shape his own story.

The historic dimension you mentioned is real. No Latino has ever been elected President of the United States. Whether that becomes a tailwind or a talking point depends almost entirely on whether the broader electorate is ready for it, and on who the Democrats put up against him.
