They still do. It is my understanding that the only change is in order to get on the ballot, each county must account for a specific number of citizens requesting the amendment. Since the law will effect all counties, each county will have its input.  This frustrates those who want all the signatories to come from only one or two counties (Denver or Boulder).   
History proves that Denver and Boulder vote for lefty causes that they happily impose on everyone and would have continued to do but for this Constitutional protection.
