Republicans control neither the House nor the Senate — and certainly not the White House. But they largely dictated the terms of President Barack Obama’s proposed tax-cut compromise, which disgruntled congressional Democrats want to discuss in closed meetings that are likely to be rowdy.

Republicans prevailed on their biggest demand: continuing Bush administration tax cuts for the wealthiest Americans, despite Obama’s 2008 campaign promise to let them expire for households earning more than $250,000 a year. Obama, while acknowledging Democratic unrest, agreed to extend the tax breaks for two years, whereas Republicans wanted a permanent extension.
