Obama attacks McCain on healthcare

In his first campaign swing as the likely Democratic presidential nominee, Barack Obama visited Virginia to mock Republican foe John McCain's healthcare proposals. Obama said special interests represented by the influence of lobbyists had blocked progress on issues like healthcare for too long. Obama critcized McCain's healthcare plan for weakening the employer-based insurance coverage system. McCain's plan would use tax credits to help shift to a more open-market approach where people could choose from competing policies.
