Colorado lawmakers are gambling that voters want sports betting Anna Staver, Denver Post · October 26, 2018 at 12:52 pm Two Colorado lawmakers want to take a gamble in 2019. A bipartisan duo think they can convince two-thirds of their colleagues and a majority of voters to legalize sports betting throughout the state. Republican gubernatorial candidate Walker Stapleton is so sure it’s happening that he’s already telling voters on the campaign trail how he would spend the tax money from sports betting. However, it’s far from certain that proponents can clear all the hurdles and make all the necessary deals in just a year’s time. Also, while Colorado has been at the forefront of converting another black market — marijuana — into tax dollars, the state has taken a more cautious approach when it comes to letting citizens lay down money on games of chance. Voters have crushed eight previous attempts to expand gambling.
