HOWARD KURTZ: The blue wave looks real until you look a little closer.

It’s like watching some sci-fi game with players competing on 470 different fields. Which is your basic definition of crazytown. No human being, without mainlining AI into his or her arm, could possibly track so many contests, so we bounce from one race to the next, with buzzers and bells, like a pinball machine.

Look! Charlie Cook is moving 18 House races in the Democrats’ favor! This is o-vah! The blue wave is getting stronger. Put a cork in this one, it’s done!

But wait a minute. The Republicans have a huge cash advantage. Big-time Democratic donors, for whatever reason, are sitting on their checkbooks. Don’t they realize the stakes? Are they all blinded by the sun on their private islands?

No cockiness, please.
