I believe you posted your data right before stupid little Lake county finally was the LAST to turn in their final numbers. The republican swing came down to 19.8%, but still quite large
And for what it's worth the Dem swing in San Mateo county was 0.002% haha
P.S. The swing in Sonoma and Ventura counties was 4.97% each, so slightly under the 5% benchmark
