Dear Cable Pundits, THERE ARE 2.6 MILLION CALIFORNIA BALLOTS LEFT TO COUNT.

1. Is this enough to tip the final results for

anyone? Regardless, I support holding off on calling the winners until every vote is counted or it is statistically impossible for a challenger to catch up with the leader.

2. My point is

that CNN and others were premature is saying no one shoed up.

3. They wanted to get home for dinner?

It is annoying, I always wait until the day after an election to check out the results. I don't think it is in the public's best interests for pundits and networks to call an election. They don't even give anyone time to review the results or prepare a concession speech.

5. They have to verify every signature on mail-in ballots.

Takes a while in a state the size of CA.

4. Most of the people I know vote via mail in ballot.

They are all Dems too. I take my ballot to the polls since I love to be part of the whole process...civic pride. The night of the election the local news people went to the polls and they said that it would take a couple of days to count them all. In San Diego 1/3 of the votes were from new voters and most were Dems. That is good news.
"While results aren't final yet — and may not be for some time because of many mail-in ballots — early results indicate those costly investments paid off."

These are the results from San Diego with 100% of polls reporting, but as the OP state's, tons more are being counted.
