Tonight will probably decides the U.S. elections. Expectations are Barack should win. In doing so, he is likely to overdo it, and overeacting. Thus, everyone will notice that he goes overboard.
Therefore, if Barack is to win tonight, he has to skillfully and thoughtfully push Mitt to the corner and force him to make a huge blunder, error or mistake. Otherwise, even if Barack provides the best performance this evening, Romney will be the winner.
I repeat, solid performance is not enough to save Barack tonight! Only if he push Romney to make a collossal blunder the momentum will be on his side tomorrow morning.
If Obama fails to force Romney to make a huge, big, desastrous, collossal, and unbearable blunder; the elections will be over tonight. Mitt will be the next president.
Mark my words.
