Do not rest until the polls close - no matter what you hear, good or bad - turn out, turn out, turn out! Get those “big numbers” in the Romney areas even higher until the polls close.
I remember in 2004 all the talk about “huge turnout” in Kerry areas and exit polls supposedly showing he was going to win easily, it was over, etc. Whether we hear something similar again, or better news - do not let up - turn out the vote!
