WASHINGTON — In the weeks since the January riot at the Capitol, there has been a raft of stories about voters across the country leaving the Republican Party. Some of the numbers are eye-catching and suggest that the GOP may be shrinking before our eyes, but a closer look at the numbers over time shows that a larger change has been working its way through the party for some time.

To be sure, the headlines from the last few weeks have been striking, with multiple states reporting large declines in Republican voter registrations.
