What if Fort Sumter Had Not Been Bombed Starting the Civil War?

It was April 12, 1861 that the Confederates bombarded Fort Sumter in the Charleston, SC harbor. Fort Sumter became a political issue in the 1860 presidential election. Abraham Lincoln won the election with only 38% of the vote (2 democrats took 60%). If Stephen A Douglas had won would that have saved 700,000 lives and freed the slaves at a slower pace? Would it have reduced Jim Crow laws and the number of lynchings?
