WASHINGTON (AP) — Republican candidate Mitt Romney seems to have gotten the message from GOP critics.

The party's presidential nominee plans to spend more time talking about his policy proposals in the coming weeks — a tacit acknowledgment that it will take more than criticizing President Barack Obama on the economy to win in November. By doing so, he's heeding the advice of Republicans who have been pushing him to fill in the gaps for voters still trying to understand what a Romney presidency would look like as polls show the president ahead nationally and in key states.

But don't expect new proposals or any additional details about Romney's plans. He's mostly repackaging previously announced positions as he grapples for a way to curb Obama's momentum before next month's debates. Romney aides, meanwhile, are working behind the scenes to calm dissension in the GOP ranks and reassure nervous donors and consultants about the state of a race some Republicans worry may be getting away from their nominee.
