The Reuters poll has a history of very being bouncy.
The 43% number was probably an outlier. No other internet or land line poll has ever had him that high, so this 12 point drop is probably a little bit exaggerated.
On the other hand, these silly media feuds don’t do him much good long term. He has his base of support of around 25-30% but he’s not going to expand out of that base unless he becomes more disciplined as a candidate.
I agree Reutuers is a very bouncy poll, the problem is that Trump’s campaign is poll dependent and gives him an aura of inevability. So, if Trump starts to fall to number 2 or 3? Does he change his campaign strategy and lay off the polling?
