But he's not likely to push as hard to extend income tax breaks for high earners since that's "in play as a give-up for Republicans" in budget negotiations with Democrats, said William Beach, director of data analysis at The Heritage Foundation, a conservative think tank.
Critics say making the tax cuts permanent will only add to budget woes as policy-makers wrestle to get control of an expected surge in costs from Medicare, Social Security and possible reform of the Alternative Minimum Tax.
Bottom line: President Bush may have a harder time convincing Congress to preserve breaks for upper-income households than he will for middle and lower income taxpayers. That's because some of his tax cuts - such as the higher child tax credit, the creation of the 10% tax bracket and increased marriage penalty relief draw bipartisan support.
