Virginia Gov. Bob McDonnell is the latest Virginia Republican to oppose legislation in his state that would replace the state's winner-take-all method of apportioning presidential electoral votes with one that awards one vote to the winner of each congressional district.
Under the proposed system, President Barack Obama would have lost Virginia to Mitt Romney despite winning the state's popular vote.
A spokesman for McDonnell says the governor "believes Virginia's system works just fine."
Similar legislation is pending in Wisconsin and Pennsylvania, states also won by Obama in November. Republican National Committee Chairman Reince Priebus endorsed the concept last week. Other GOP leaders have expressed support for the idea as a way to rebound after last fall's defeats.
Democrats say the effort is a power play to rig elections and steal with a legislative majority what Republicans could not win with the ballot.
