Why are you applying the factor scores to only 24 states? I don't see that in your discussion. You can always see if a set of factors from one sample is replicated in another sample, but you can't assume because you did find it in one you will find it in another. This is true of any statistic, and would have been true even if you were doing 49 states. And the 24 states data of course could be substantively different from the 49 because the states vary.

You might want to look at this in terms of your error.
