The #NeverTrump movement has reason to be worried. We still have to wait for polls to close, but in the VERY early votes are in and Donald Trump has a solid lead according to CNN.
There are still MANY MANY votes to cast and count, and no one should be dissuaded from doing so. If Rubio does eventually lose, it's of course a huge blow and makes it a near mathematical impossibility to win.
BUT nothing is decided yet.
Stay tuned for the final results in about an hour when the remainder of the polls close in Florida.
