So is there a good chance for Nelson?
Outside of it actually being a machine error in Broward with the undervotes, very unlikely, though not impossible.
But what's the chance of that? As noted the under votes, or possible under counts, are very highly concentrated geographically. While I'm probably just Wishing on a Star here, then at least slightly indicates it may be a machine error.
It's possible, but I wouldn't say the under-vote in the specific area is indicative of anything. I believe its been shown that in that area there wasn't a House race or other election below, so the Senate race was only one under the instructions which makes it quite possible it simply wasn't seen.
Unfortunately it's more than likely than not we lose the FL-Sen because some people didn't look at their entire ballot.
