Economy May Delay Work on Obama’s Campaign Pledges - NYTimes.com

WASHINGTON — Confronted by the worst financial crisis in generations, President-elect Barack Obama and his Democratic allies in Congress are preparing to delay some of the promises he made on the campaign trail to avoid political distractions and focus on reversing the economic slide.

Although Mr. Obama has not publicly identified which priorities will have to wait, advisers and allies have signaled that they may put off renegotiating the North American Free Trade Agreement, overhauling immigration laws, restricting carbon emissions, raising taxes on the wealthy and allowing gay men and lesbians to serve openly in the military.
