Self-styled militia members who seized federal property in rural Oregon in an effort to galvanize opposition to the U.S. government appear to have made a tactical error — potential allies say they picked the wrong battle.

As armed anti-government activists occupied a snowy wildlife refuge for a third day to call attention to a land-use dispute, militia leaders from similar groups across the country criticized the seizure of federal land and a building.

The protesters have said they aim "to restore and defend the Constitution" to protect the rights of ranchers and ignite a national debate about states' rights and federal land-use policy they hope could ultimately force the federal government to release tracts of Western land.
