Yes, Marco Rubio still has a chance for the Republican nomination because he is considered by many Republicans as the future face of the Republican party. Although Rubio only won the state of Minnesota on Super Tuesday, his supporters are still optimistic that his message will soon get through to voters.
No, Marco Rubio does not have a chance for the Republican nomination. There has never been an instance where a candidate has performed well on Super Tuesday, Donald Trump, and not received the party's nomination. It would require that all of the other Republican candidates to drop out, leaving Donald Trump in a two man race, which would potentially allow for Rubio to be successful, but the likelihood of this is highly improbable.
Marco Rubio has little to no chance to secure the Republican nomination for President of United States. He is too much a part of the political establishment, in spite of his repeated attempts to have us believe otherwise. His record speaks for itself. And, his psychotic rants are doing nothing to help him in his quest.
The math just does not add up. There is such a massive movement of electorates flocking to Trump that it's almost impossible for Rubio to catch up in the delegate count. The Republican Party is so fractured to the point where the people are willing to turn to anyone with even a mild hope of beating the democrats. It is sad to watch.
