I'm thinking of a whole number between 1 and 3.
Is it "speculation and untrue" to say I'm thinking of 2 even though I didn't say it explicitly? Of course not. There is no other number I could be thinking about!
Similarly, it's neither speculation nor untrue to say that Ron Paul is suggesting he will vote for GJ. There is no other candidate he could be referring to!
