Howard Fineman appeared on Keith Olbermann Thursday to discuss the GOP's newfound opposition to the "omnibus" spending bill, which contains millions of dollars in earmarks that Republican leaders originally supported.
"The main headline here is that the tea party is in control," said Fineman. He went on to explain that conservative leaders didn't anticipate tea party opposition to their willingness to compromise with the White House about tax cuts for the wealthy.
"Republican leadership was blindsided by tea party anger about the tax bill," he said. "The tea party won this round."
