Based on the following, it would appear the best way to beat this might be petitioning congress.
As the federal capital, the constitution grants the United States Congress exclusive jurisdiction over the District in “all cases whatsoever.”
At certain times, and presently since 1973, Congress has allowed certain powers of government to be carried out by locally elected officials. However, Congress maintains the power to overturn local laws and exercises greater oversight of the city than exists for any U.S. state. Furthermore, the District’s elected government exists at the pleasure of Congress and could theoretically be revoked at any time.
“...the District’s elected government exists at the pleasure of Congress and could theoretically be revoked at any time.”
Something for the GOP to tackle next session! Hah!
What Congressional treatment would not require the signature of the pResident?
