What does one make of moderates favoring Trump over Bush? Is it just due to name recognition of Trump vis a vis the others, other than Bush, as to whom it suggests a personal disaffection with him at the moment, and thus a desire to seek out alternatives?
Well, Bush has a 36% Favorable, 30% Unfavorable rating among Republican moderates. He's in positive territory, but its definitely a lackluster performance. Many of his competitors have better ratings among moderates (including Walker and Rubio).
Meanwhile Trump has a 35% Favorable, 54% Unfavorable rating among the same group. His favorability is much better among conservatives, but his vote share doesn't go up. This seems to support the idea that Trump is winning low information voters.
