Expanded hiring in manufacturing, where payrolls increased by 50,000 in January on top of months of general job growth, led to hiring in the service sector, including business and professional services, which added 70,000 jobs, the biggest gainer.
That category, which includes accounting, computer design, law, and engineering, derives some of its strength from serving manufacturing companies, Rankin said.
The Dow Jones industrial average shot 160 points higher, to 12,865, in the first hour of trading. That is 55 points higher than its highest close since the financial crisis struck in the fall of 2008. The Dow closed the day at 12,862.23, up 156.82.
The jobs report "fuels a more optimistic climate for the president, and incumbents in general benefit from a sense that the economy is moving in the right direction," said political science professor Chris Borick, director of the Muhlenberg College Institute of Public Opinion.
"The economy is everything," Borick said.
Obama enjoyed a boost in poll ratings last winter, when positive job growth seemed to indicate the economy was strengthening. But as job growth slipped over the summer, so did Obama's ratings, Borick said.
Rankin said that consumers and businesses "are increasingly able to tune out the white noise" of fractiousness in Washington and the constant ups and downs of world economic news.
That will lead, he said, to an increased willingness to spend, invest, and hire.
The Labor Department revised recent payroll statistics upward, from 100,000 to 157,000 in November and 200,000 to 203,000 in December.
Friday's numbers, while good, don't seem to square with recent headlines.
