Given these data, two factors would indicate that the crossover voting laws may spell trouble for Hillary:
If she only leads Obama by 5 to 10 points among Democrats when she has an 83-13 favorability rating, she will likely do much worse among independents.
The passion and the depth of animus against Hillary, particularly among Republicans and Republican-leaning independents, may be so intense as to motivate them to participate in the Democratic primary in great numbers.
Most current polling fails to capture the likelihood of crossover voting. News media surveys generally ask Democrats what they think about the Democratic field and Republicans what they think about the GOP contenders. Since half the states do not permit independents, much less members of the opposite party, to enter the primaries, few national samples ask independents what they are likely to do.
Those that do tend not to divide their samples along the lines of each state’s law; fewer still ask Republicans if they will vote in the Democratic primary. So crossover voting is a blind spot in most current polling.
All strategists and pollsters need to amend their thinking to view the primaries as the three-dimensional processes they really are.
