On this date in 1787, at the Constitutional Convention, the following vote was taken (which passed):

To give the federal government the power “To make laws for organizing arming & disciplining the Militia, and for governing such part of them as may be employed in the service of the U. S.”

John Langdon of New Hampshire attempted to smooth over the rift between states-righters and federalists:

“Mr. Langdon said he could not understand the jealousy expressed by some Gentlemen.
“The General & State Governments were not enemies to each other, but different institutions for the good of the people of America.
“As one of the people he could say, the National Government is mine, the State Government is mine.
“In transferring power from one to the other, I only take out of my left hand what it cannot so well use, and put it into my right hand where it can be better used.”

After the vote, Elbridge Gerry of Massachusetts took the floor:

Mr Gerry [sarcastically, apparently]: Let us at once destroy the State Governments, have an Executive for life or hereditary, and a proper Senate, and then there would be some consistency in giving full powers to the General Government. But as the States are not to be abolished, he wondered at the attempts that were made to give [the federal government] powers inconsistent with their existence. He warned the Convention against pushing the experiment too far. Some people will support a plan of vigorous Government at every risk. Others of a more democratic cast will oppose it with equal determination, and a Civil war may be produced by the conflict.

Kind of jumps out at the reader now, in hindsight.
