PORTLAND, Maine (AP) — A Republican congressman is brushing off criticism from conservatives angry that he didn't vote to repeal President Barack Obama's health care law. "Casting yet another symbolic vote for full repeal of the law, without any replacement legislation, simply distracts us from the work that must be done to drive costs down, restore access to care and make healthcare work for everyone," he said in a statement. The congressman wants to replace the law with a "free-market alternative," like one outlined by some GOP members this week that would eliminate insurance marketplaces and abolish taxes the law imposes on medical devices, among other things. Poliquin hasn't endorsed the plan, but said any replacement must require health insurance companies to cover people with pre-existing conditions and help the more than 60,000 Maine residents who already have signed up for coverage on the exchange.
