Many political insiders are wondering how someone with so much promise as Marco Rubio could fall so far so fast. For years we've heard Rubio is the future of the Republican party. Now that his dreams of capturing the nomination have been obliterated, the chief question seems to be: what's the future of Marco Rubio? His term in the Senate is up in January and he was forced to give it up to run for the presidency last spring. While he could run for governor in 2018, last night's resounding loss to Trump in Florida suggests he still has some work to do in his there. If things go well with Trump, Rubio will probably sit out the 2020 GOP race. But, if Hillary Clinton becomes President or if Trump bottoms out, a wiser Rubio might step up again.
