Yahoo News reports:
Grover Norquist, the influential conservative activist who is the president of Americans for Tax Reform, will endorse Richard Mourdock over Dick Lugar before next week’s Republican Senate primary in Indiana, Yahoo News has learned.
Lugar, who has represented Indiana in the U.S. Senate since 1977, has never signed Norquist’s “Taxpayer Protection Pledge” never to raise taxes. A majority of Republican lawmakers–and some Democrats in conservative districts–have signed the Americans for Tax Reform pledge.
