Here are some of their telling statements from the Constitutional Convention of 1787.
"A popular election in this case is radically vicious. The ignorance of the people would put it in the power of some one set of men dispersed through the Union, and acting in concert, to delude them into any appointment." -- Delegate Gerry, July 25, 1787
"The extent of the country renders it impossible, that the people can have the requisite capacity to judge of the respective pretensions of the candidates." -- Delegate Mason, July 17, 1787
"The people are uninformed, and would be misled by a few designing men." -- Delegate Gerry, July 19, 1787
Still seems rather true to me.
How else can you explain the current President winning the popular vote?
