I wanted to thank you, Perotista, for keeping up the tally.
When the elections happen, it will help to filter the bloviators and hyperventilating from the media about sweeps and waves and mandates. So much of the results are already baked, or manipulated, in that we're really only talking about four dozen or so seats in all of Congress, and maybe two dozen primaries of any significance. Many of the latter can be predicted months in advance, anyway.
But, I, at least, haven't taken the time to quantify the actual manipulation as you have. It's a service to us all.
