I saw Carville too. I wish people could stay calm. If there was a race with a only a favorite, an underdog, and a never-gonna-happen like we've had before, then perhaps a 2020 apparent winner would have emerged from Iowa.
But there is a slate of appealing candidates, a couple of hangers-on, and a potential "spoiler". All of them are "Trump capable", at least. And at least right now, the only campaign for which this vote is not looking good for, compared with expectations, is Biden. The media is salivating at declaring an apparent winner for all of 2020 as soon as possible - that's their game, not yours - just keep up with what your favorite campaigns are saying and doing. Iowa is only 41 out of 1900+ total delegates.
Now, three campaigns made mistakes this time. Biden, by acting like Trump and firing off lawyer letters and suggesting injunctions. Also, by not really leaning into Iowa. Buttigieg, by leaning in to victory talk - not last night, but today. Sanders, by having campaign staff on tv complaining about mythical shady backroom deals and "oligarchs" in the race without giving voters in flux reasons to ditch those folks and go for Sanders. Perhaps appealing to the faithful - but even with the Iowa positioning right now, they need to increase their outreach and its effectiveness. And also being in Iowa midday today complaining while candidates already went to NH.
Buttigieg and Sanders should not have released their numbers. I get it, they want to tell donors and voters to keep going/giving, but don't put your thumb on the scale, and don't run when you are not being chased. They lost a bit of luster. And it's a bit Men Behaving Badly.
As for Shadow, they'll change their name and start again. There's no appgate.
Please take a moment to breathe when you have time.
