Don't you mean "erases Barack's lead"? Your headline makes it sound like Romney's winning in a landslide.
I think most people would understand that to "erase a lead" implies pulling even, not a landslide.
Which is exactly why he said it should say "erases Barack's lead" instead of what Naso actually posted that is "erases Barack". I guess reading comprehension isn't something tested for MENSA membership.
I guess you do need to be in Mensa to understand that virtually no one says "erase" to mean "destroy" or "wins in a landslide."
Naso, for BRTD's sake, use tiny words.
Many people use "erase" as in "to destroy".
Maybe he used the word "Erase" as a shout out to you Eraserhead, or maybe David Lynch.
