correct version:
At a rally in Anderson, Indiana, Obama responded to critics who say he has not been tough enough in responding to Clinton's verbal jabs.
"I am not interested in fighting people just for the sake of scoring political points or getting on the cable news shows. If I am going to fight somebody, it is going to be fighting over the American people and what they need. I will fight for health care. I will fight for a good education system. I will fight to make sure that people have good jobs and good wages. I will fight to the death to make sure that America is safe. Those things I will fight for. That is what I will fight about." Polls show that Obama has a substantial lead in North Carolina, and that in Indiana, the two Democrats are either even or Obama has a slight lead.The presumptive Republican nominee, Senator John McCain, did not make any campaign appearances on Saturday, after appearing in the Southern state of Arkansas Friday with former Governor Mike Huckabee, a one-time rival for the Republican presidential nomination.
