Rubio OK with school speech?

Florida Senate candidate Marco Rubio (R) seems to be OK with President Obama addressing the nation's school children next week....sort of.

Here's what the Florida conservative tweeted:

I have no problem with President giving political speech to kids........if his name is REAGAN!

Liberals have pointed out that Ronald Reagan gave a speech to school children too. But Rubio isn't clear here: does he have a problem with OBAMA's speech?
