This is probably a bad idea for a poll. I just want to apologize right now for starting this poll. I'm already embarrassed...
Here's one opinion:
Top 10 Most Influential Presidents
By Martin Kelly, About.com Guide
"Of the 43 men who have been president of the United States, there are some truly clear choices of who were the most important and influential presidents.
1. Abraham Lincoln
Abraham Lincoln saved the Union during the American Civil War. His leadership during the war was one of no compromise but at the same time understanding that he would eventually have to unite the states once the North won the war. His actions eventually led to the abolition of slavery across the United States."

Does everyone agree?
How long was Killing Lincoln by Bill O'Reilly the New York Times best-seller? It's still in the no. 2 position right now.
I can't find anyone that's critical of Honest Abe. I guess this is a non-subject to everyone. I apologize again, I'm sorry.
