King County, probably unlike the others, is an area where the local Democratic party still maintains a monopoly on registrations.
P.S. - I wonder if there are many counties in Texas which switched from Dem to GOP from 1960 to 1964...
Not from what I have gathered. My grandmother, a lifelong Texas Republican (a Goldwateresque conservative, not the batsh*t insanes that have taken over the GOP) says that the GOP only started getting momentum during the late 60's and 70's. Let it be noted that in 1961 John Tower was the first Republican US Senator elected since the days of Reconstruction. Also, from 1961-1965 Texas only had two Republican US Representatives. This would've been around the time when the Texas Democratic Party Primary stopped being considered the unofficial election for whatever office candidates were running for.
