Your research is in error. It passed the House on May 10, 1860. It passed the Senate in early March 1861 and was signed into law on March 2nd. Prior to that, Lincoln had pledged to make it a top priority in the next session if it did not pass by his inauguration on the 4th.
You tried to BS people in talking about the House of Representatives. They could pass bills until the moon turned blue. It meant nothing if the slave states could jam up the Senate. And they willingly and foolishly gave up that veto power on freedom and progress by walking out.

Correct me if I'm wrong, but had not 14 Senators from the 7 Deep South states already left Washington by early March of 1861?
