The deadline for Washington DC mayor, Vincent Gray, to act on B19-90, the bill to move both the presidential primaries and the primaries for district offices to the first Tuesday in April in presidential election years is tomorrow, Friday, April 29. The DC Council passed the bill back on April 5 and transmitted the legislation to the mayor on April 14. After that point, the mayor has three options: 1) sign the bill in which case it becomes an act, 2) do nothing in which case it becomes an act, or 3) veto the bill in which case the council can choose to override the veto.
Given that the mayoral review period has almost concluded, the most likely action -- inaction, really -- is for the mayor to do nothing, thus enacting the law. Now, technically, the act would then go to the US Congress for review as well, but on non-controversial legislation like this, that should prove to be nothing more than a formality. That has been the case in the past anyway.
For our purposes here at FHQ, DC will move to the April 3 line on the calendar should Mayor Gray fail to act on B19-90 tomorrow.
