MINNEAPOLIS (AP) — President Barack Obama assailed critics of his health care initiative Saturday, seeking to grab the megaphone from his opponents and boost momentum in his drive for congressional passage of his chief domestic priority. “I will not accept the status quo. Not this time. Not now,” the president told an estimated 15,000 people during a rally that had every feel of a campaign event, right down to chants of “Fired up, ready to go!” and “Yes, we can!” Days after urging Democrats and Republicans in Congress to come together, an invigorated Obama said his plan incorporates ideas from those on both sides and he promised to continue to seek common ground. “If you come to me with a serious set of proposals, I will be there to listen. My door is always open,” the president said. But he warned that he wouldn’t waste time with people who have decided “that it’s better politics to kill this plan than improve it.” He also said he wouldn’t stand by while special interests “use the same old tactics to keep things exactly the way they are.” —-Contact The Daily Reveille’s news staff at [email protected]
