The problem is, the Republicans aren't usually leading, they are usually down 5 points or so, thats why Reps get optimistic. This time the REP is up double-digits. So no, the "pattern" doesn't apply.
That applies to Forrester both times, but Kean was leading at this point (albeit by very little with high undecideds)
Its just that Christie (according to the polls) does not even need a break of undecideds, he just needs his voters not to leave his camp
Kean and Menendez were both leading at this point depending on the pollster, and Kean never was out of the low 40's. Christie has led 15 straight polls, and 3 out of the last 4 is over 50%. This is COMPLETELY different.
