Ted Cruz has found his wedge issue against Donald Trump on Nevada: land ownership. Cruz has begun airing his first television ad in Nevada that attacks Trump as too trusting of the federal government’s power in the West, setting up what could be a key contrast in the short sprint between South Carolina and Nevada’s GOP caucuses on Tuesday. Trump has said public lands are “an absolute mess” and vowed to fix them. But he has expressed reluctance to turn them back over to the states. Republican candidates and allied groups have spent very little money on Nevada advertising, with most pouring cash into South Carolina that votes just three days prior. Cruz’s super PAC recently announced it too would begin television time in the Silver State, beginning a $2 million campaign in a state where Trump has a 26-point lead.
