Mitt Romney easily survived his first test of the 2012 campaign here Monday night, cruising through a debate with six Republican rivals who were more interested in attacking President Obama than in turning their fire on the former Massachusetts governor.

In his first debate of the campaign, the nominal front-runner for the GOP nomination seemed eager for the spotlight. Through two hours of questioning, he delivered a steady performance, made no obvious errors and stuck to his campaign game plan of focusing his message on the president and the economy.
