I'm not a fan of over reliance on polls this early, and I'm not a fan of any reliance on national polls (because it is pointless to measure the efficacy of the campaigns in the states where the campaigns are not yet operating), but I think polls in states where the candidates are actively campaigning can be a good snapshot of how well the campaigns are succeeding at getting out their candidates' messages. In that context, here is what the American Research Group has just released for Iowa, New Hampshire, and South Carolina:
