A Democratic campaign office here usually would be quiet this time of year, a few weeks after the state’s legislature wrapped up work and lawmakers headed off to summer vacations.

But even though it’s not an election year, the office is in full campaign mode, with volunteers working the phones and reviewing maps in anticipation of a new front of modern campaigning — the recall phase.

A handful of Democratic state lawmakers in Colorado face recall petition efforts in what looks to be the first wave of fallout over legislative votes to limit gun rights. In an era in which recall efforts are booming, from governor’s offices down to town councils and school boards, the Colorado efforts will serve as the first test of gun-rights groups’ ability to punish elected officials who expanded gun control laws after last year’s Aurora, Colo., and Newtown, Conn., shooting massacres.
