It's two down, eight to go for the GOP "Contract With America." The House passed legislation requiring Congress to pay for regulations it imposes on states and local governments today, in a bipartisan 360-74 vote. The Senate approved its version of the Unfunded Mandates Reform Act, 86-10, last Friday. President Clinton has voiced support for the bill, and is expected to sign it into law. Today's vote puts a second check mark in Newt Gingrich's little book, next to last week's balanced budget amendment victory.
