I still think Wesley Clark Ashley Wilkes er... George McClellan would have wasted a lot of good opportunities to end it sooner rather than later. ;-)
He certainly did waste opportunities. And your comparison to Wesley Clark is a good one. McClellan was a great organizer, but no fighter (the Peninsula Campaign for example). And I believe the people recognized that during the 1864 Presidential election. Not to say that was the only reason Lincoln was re-elected.
McClellan and the democratic party of the day are just like Wesley clark and the democrats of today. McClellan ran for office against lincoln as the candidate of the democratic party. He was running on a platform that there should have been negotiations with the South. What would our country look like if he had won? How would that affect another disgruntled region like New England? Let alone what would that mean for the western expansion of the US. The democrats of the day wanted to cut and run. Interesting to see history repeat itself.
