By Edwin Chen Jan. 11 (Bloomberg) -- President-elect Barack Obama said reviving the U.S. economy will require scaling back on his campaign promises and personal sacrifice from all Americans. âI want to be realistic here, not everything that we talked about during the campaign are we going to be able to do on the pace we had hoped,â Obama said in an interview on ABCâs âThis Weekâ program broadcast this morning. âEverybodyâs going to have to give.â I'm not sure which is worse. That Obama wasn't intelligent and far sighted enough to know this while he was making all those promises. Or that the sheeple that elected him weren't intelligent and far sighted enough to realize it before they voted. I guess it's water under the bridge now.
