Lede: BANGKOK — Thailand’s high court disbanded the ruling party for electoral fraud and brought down the government on Tuesday, prompting antigovernment protesters to declare an end to their debilitating weeklong blockade of Bangkok’s airports.
Summary lede stating place and time. This has been an ongoing and updated story, so it packs in a lot of material: the inital protests, the reason of the protests, when they stopped and why.

Nut Graf: I'm actually a little confused about which paragraph is the nut graf, and also the significance of the nut graf. Here are the next two paragraphs:
Leaders of the disbanded party, People Power, said they would reconstitute the government under another party name and hold on to power, although the count of parliamentary votes was not assured.
But the protesters — who had also occupied the prime minister’s office for more than three months, calling for the ouster of the government — said they would end all their blockades by Wednesday morning.

It doesn't really sound like anything's going to be changed but the name of the political party in power. And even then, "the count of the parliamentary votes was not assured," about that, so the name might even stay the same. I'm a bit confused about why the protestors have ended the blockades.
The next paragraph goes into the history of Thaksin, who was the prime minister before the 2006 coup, and how the current government is corrupt and has ties to Thaksin still.

I found a bit more of an explanation a few paragraphs in: The ruling disbanded not only the governing People Power Party but also two smaller coalition parties; the court found that they had committed fraud during the elections last December that brought them to power. It forced out Prime Minister Somchai Wongsawat, a brother-in-law of Mr. Thaksin’s.

The article switches between a scene in the airport of protestors celebrating and their comments and background information on the protests and the government.

The article ends by giving more history of Thai government, with this little gem: In September this year, Mr. Somchai’s predecessor, Samak Sundaravej, was forced out after less than eight months in office when the court ruled that he had unlawfully accepted payments to appear on television cooking shows while prime minister.

Not really a fizzle ending, at least it shouldn't be. If I were to read this story in print and that final paragraph hadn't been there, I wouldn't have enjoyed the article as much.
