Politico’s Jennifer Haberkorn reports that, after four election cycles of ducking, dodging and tiptoeing around Obamacare, Democrats this time around have “a unified message blaming Republicans for ‘sabotaging’ the health care law, leading to a cascade of sky-high insurance premiums that will come just before the November midterm elections. They’re rolling out ads featuring people helped by the law. And Tuesday, they’re starting a campaign to amplify each state’s premium increases — and tie those to GOP decisions.” Democrats are also focusing on rising health care costs, projected Obamacare premium spikes and prescription drug prices, looking to hang those increases on the GOP.
