Overall, these sources collectively support the claim that there has been a notable shift toward Republicans in voter registration and party affiliation across many states from 2020 to 2024. This shift has indeed raised alarm among Democratic elected officials as reported by The New York Times. However, exact numbers of '30 states' come primarily from analyses cited by UnHerd and The New York Times rather than an official government source.
Limitations include the lack of direct official government confirmation of the exact number of states with shifts and potential variability in how party affiliation changes are measured. Also, some sources focus on voter registration while others discuss party identification or voting behavior, which are related but distinct metrics.
