U.S. Constitution question

[veronica_rich]

Would somebody who's a better scholar than I please point me to the section in the federal Constitution where a supermajority vote to pass legislation is required in any instance other than that following a presidential veto?

I keep hearing a simple majority vote in the Senate and House - referred to now as "reconciliation" (I haven't heard that word in 16 years of being a reporter, regarding taking a vote, and I've covered Congressional legislation) - isn't legal. This runs counter to what I remember learning in school. It's been 20 years since I was in school - would somebody please point me to what I've forgotten or missed?

Thanks!
