the mystery to me is why would
that be your go-to canned zinger?
like
1) it had no obvious relation to the context or question ever
2) the phrasing - "dispel with this notion" etc. - would sound stilted even were it semantically correct
3) on the surface it's "vote Rubio because Obama knows what he's doing", which,

4) even if you parse the actual argument he's making, it's confusing and doesn't exactly smell like red meat - can't he at least throw in some scary example of the iniquity of The Rest of the World?
is there some context I'm missing that would make this resonate with the GOP base?
