Getting beyond a day’s skirmish on the campaign trail, we’re not wild about either candidate’s treatment of this issue. We have been ambivalent about legalizing recreational marijuana, preferring to wait until we’ve learned more from other states about the social and health costs, but even if we assume it’s inevitable, there’s reason to be wary of tying a pre-K expansion to it. If our experience so far with medical marijuana tells us anything, it’s that Maryland is fully capable of screwing up a sure thing like legalizing pot. Best case scenario, it would take time for the state’s revenues to ramp up to the levels Mr. Jealous is counting on — Colorado took four years to do so. And whether or not the General Assembly passes marijuana legalization in the form of a constitutional amendment requiring approval by the voters (a sensible idea Mr. Hogan has floated), the chances are high that the matter would be petitioned to referendum, delaying implementation by a couple more years. If universal pre-K is important (and we believe it is), Maryland should figure out a simpler way to fund it.
