(CNN) - As voters headed to the polls in West Virginia in a contest Hillary Clinton is expected to win, a memo released by her campaign argued that Barack Obama had waged an “aggressive campaign” in the state – and that a loss by the Illinois senator there would raise troubling questions about his general election chances.
"In the face of grim poll numbers, the Obama campaign has attempted to dismiss today's outcome despite the fact that Sen. Obama has outspent us on advertising, has more staff in the state, and more than double the number of offices,” said the campaign in an e-mail sent to reporters Tuesday.
“He has also benefited from the support of the most high-profile endorsers in West Virginia-Sen. Jay Rockefeller and Congressman Nick Rahall. By every measure, the Obama campaign has waged an aggressive campaign in the Mountain State," they said.
The Obama campaign has been looking to downplay the results of West Virginia’s vote, spending the evening in Michigan, a fall battleground. Obama trails Clinton by 30-40 points in recent polls of the state’s primary voters.
