Most of the Party of Regions' protesters are less interested in Klitschko's political views though, than getting their pictures taken with him.
The tweet says, "This is not a contemporary art exhibition, this is a revolution."

Tuesday wrap-up (final post for the evening)
-- Early in the day, the Ukrainian parliament voted against holding a vote of no confidence in the government. They needed 226 votes, but only came up with 186.
-- Angry crowds chanted "shame" outside the parliament. By late afternoon, Independence Square had swelled to at least 10,000 protesters again and the leaders of the three main opposition parties led a crowd of thousands to the presidential administration building. Most, including the opposition leaders returned to Independence Square.
-- Ukrainian Prime Minister Azarov, who survived a potential no-confidence vote this morning, apologized for violence against protesters, but also harshly condemned the continuing demonstrations and the occupation of government buildings. He said the actions are "unconstitutional" and "illegal."
-- Ukrainian President Viktor Yanukovych has arrived in China to begin a three day visit, which will be followed by a trip to Russia. Still, he has promised he remains committed to EU integration.
-- Until late November, Yanukovych had said he intended to sign a pact with Europe, but backed out after pressure from Moscow. He also refused to allow former Prime Minister Yulia Tymoshenko to leave prison for medical care in Germany -- a key European demand.
-- The encampment in Independence Square remains, with barricades meant to protect it from riot police continuing to grow and crowds of protesters camping out overnight. The city administration building and the trade union building are still occupied.
More dissent among the ranks. According to the "Leviy Bereg" news site -- which was filing updates on Facebook following its lv.ua site crash -- Party of Regions deputy and Yanukovych ally Hanna Herman minced few words while discussing the failure of Ukraine's education minister, Dmytro Tabachnyk, to subdue student protesters. Speaking on ICTV, she said: "If Ukraine had a normal education minister, one who had the respect of the people, then he would have gone out and explained to the students why the EU agreement wasn't signed. And then relations would have been different. But really, could Tabachnik ever go out to the people? They'll spit on him."
