If all 435 members of the House of Representatives votes, then at least 290 must vote to override. If all 100 Senate members vote, then at least 67 must vote for the veto. A two-thirds vote is technically considered a supermajority, which is much more difficult to get than a traditional simple majority. Fewer than 10 percent of all presidential vetoes have been overridden by a vote in the chambers of Congress.
There seems to be some confusion in the press over how many votes will be needed to override President Bush's veto of the SCHIP bill. It's pretty much basic arithmetic. There are 435 members in the House. You need a 2/3rds majority of all voting members to overide a veto. So at most, 290 members will have to vote to override. That's all we know for sure. 265 members voted for the SCHIP bill the President vetoed. But 11 members didn't vote. So that means that 18 members would have to switch their votes to override the bill. Or let's say all 11 members who didn't vote decide to support it.
