Has America really been trying to screw with Eric, or is America just voting along popularity lines? If its the second, then Eric made the right move switching sides, which is what it looked like to me. He really worked at pitching the plan to Jess this week. I think Eric finally figured out that he is part of the NH and America did not like the last NH so in order to quit casting the mystery vote he better get on the other side.
Now if Eric is wrong (me too then) we should find out shortly, and then he has no chance of staying any longer.
