CHARLOTTE, N.C. Double fresh

We’ve figured out the story on those Castro twins. No, Jon Stewart, it’s not that the Dems want “an extra” in case one breaks. Clearly, it’s a U.S. plot to infiltrate the annual Eurovision song contest. This – a cracked-out thing, like “American Idol” with interplanetary costumes and insane effects – draws some 100 million viewers in 43 countries (see http://bit.ly/Q8fhbn) – five times the audience of the last Idol final.

Can we doubt these clues?

• Eurovision section in the Convention Center, right next to CBS News.

• Dark-suited men with curly, Secret Service-ish wires snaking from collar to ear, flanking that section.

• The fact that Ireland’s entry has repeatedly been Jedward (above).

See this Castro poster? Can it be anything but the first Euro-foray? Said a poster company rep: “What a great opportunity to highlight these very distinguished leaders who have a very bright future” – maybe in matching metallic outfits.

LOL (CLT) Cats

It started with the DNCC’s now-notorious cat video. ( Rachel Maddow summed up: “Um … what?” Yet here it sits – http://bit.ly/OTnLn5 – with 26,000+ views.) It progressed with writer Baratunde Thurston tweeting from Vida (oops: CNN Grill): “We agree; in future, journalists will get traffic by using cats as convention correspondents. #dnc2012.” It continued with the NYT quoting Texan Craig McCartney Thursday: “You can’t swing a cat without hitting gay people in Charlotte this week.”

So – some cattiness, to ramp up kittenfestation: Former John Edwards staffer Bridget Siegel promoted her new sex-and-politics novel here, “in a ladylike aqua sequinned skirt,” the WashPo said, insisting the book isn’t about Edwards but “an inside story on campaign fundraising.” Yeah. “Inside story.”

(A canine digression: Spaniel spotted on College Street Thursday with sign, “I bark for Obama. 28 more years.”)

Close, but no DNC™ cigar

• The Raleigh N&O insists NYC columnists can’t dis the QC: “If anyone has a right to spew vitriol on the villainous city, it’s us.”

• @ amyewalter (of ABC News): “Watch ABC/Yahoo show; learn something. Charlotte Mayor Fox just educated us: It’s ‘Charlottean.’ ” And yet, Amy: Foxx.

• @CharlesThomas7 (Chicago TV reporter): “After 6 days in N. Carolina, I hit my limit on fried chicken. Help! #Bojangles.” Charles? There is no limit on fried chicken.

Button of the day

A riff on what Rush Limbaugh called Sandra Fluke, after she said health care coverage should include birth control.

Presumably.
