Then you’re not a very good one—sorry. (And I hope you work for the GOPe.)
Whenever a Gallup or some other such poll provides data based on a subset of its total sample (e.g., presidential primary preference among Republicans) its results are only are strong as the sample size of that subset: all of the Democrats and independents that were included in the larger poll are irrelevant.
Thus, this is one of the larger GOP-only sample sizes you’ll see.
you’re outta your league. Bye.
(and I’m a damned good one…)
