According to columnist David Brooks, President Obama's poll numbers are sliding because the "insular liberals from big cities and the coasts" who control Congress don't fear him. "Months ago, it seemed as if Obama would lead a center-left coalition," Brooks wrote. "Instead, he has deferred to the Old Bulls on Capitol Hill on issue after issue" — who are flouting his priorities on health care, cap-and-trade and tax rates. "Every new majority overinterprets its mandate," Brooks concludes. "We've been here before. We'll be here again."
