WASHINGTON (AP) - After Mitt Romney's 2012 loss, many senior Republicans concluded the party must moderate its image on issues such as immigration and reproductive rights.
But some GOP lawmakers have done the opposite.
They imposed new restrictions on abortion in several states. They are strongly resisting a broad immigration bill in the House. They're waging a steady assault on "Obamacare," with some House and Senate Republicans vowing to shut down the government if that's what it takes to choke off the health care law Congress enacted in 2010.
These trends worry establishment Republicans. And they expose a growing split in the GOP.
