President Barack Obama began Saturday a four-day tour of key battleground states and the storm-ravaged Gulf Coast in the lead-up to his party’s convention, trying to blunt Republican Mitt Romney’s momentum, who vowed to bring more jobs to the country and bemoaned the 23 million people out of work or underemployed.

“If you have a coach that’s zero and 23 million, you say it’s time to get a new coach,” Romney said in retooled campaign speech in Cincinnati as the college football season kicked off across the nation. “It’s time for America to see a winning season again, and we’re going to bring it to them.”
