McCain's latest: claiming that Obama will turn the IRS "into a giant welfare agency." And this even though McCain's rationale for this claim is Obama's support for a refundable tax credit, something McCain himself supports as a centerpiece of his health care plan. Par for the course, really: if you figure in the robocalls and recent ads, McCain's entire campaign is now comprised of innuendo and lies meant to tie Obama to various stereotypes of African-Americans and of course Arab terrorism. His purported foreign policy experience hasn't been part of the campaign's message in weeks. Just black, black, black, terrorist, terrorist, terrorist.
