Sounds like a good tactic to me
From Greg Sargent today, re campaigns to get President Obama to issue an executive order banning LGBT discrimination by federal contractors:
GetEQUAL’s managing director, Heather Cronk, tells me that in the next few weeks, the group will start staging actions against Obama For America offices throughout the country. The actions will begin with small gestures and will escalate over time.Candidate Obama had pledged to issue a policy banning such discrimination by contractors; the White House recently said it has no plans to issue an executive order instituting such a policy. The White House subsequently said it "hasn't taken any options off the table."
Campaign offices seem like a sitting duck. If this works, other movements/campaigns will be left wondering why they didn't do it.
