WASHINGTON (AP) - President Barack Obama's campaign is opening a new critique of Mitt Romney, focusing attention on the Republican's economic record as governor of Massachusetts.
    
Obama's team looked to respond to Romney, who seized the GOP presidential nomination with his primary win in Texas on Tuesday night. That pushed him past the 1,144-delegate threshold he needed to win the nod.
    
Obama's advisers have said that, under Romney, the Massachusetts economy lagged in job creation and saw an increase in debt while he was governor from 2003-2007.
    
Romney's campaign, in turn, was bringing attention to failed stimulus projects and federal money given to green-energy companies like Solyndra. The solar company received hundreds of millions of dollars from Obama's administration only to go bankrupt.
