In 1852 and 1856, One potential candidate for the Whig/Republican Parties was New York Senator and future Secretary of State William H. Seward of New York. In 1852, he didn't run at all and in 1856, he was suggested for the Republicans but requested to have his name withdrawn, along with Ohio Senator Salmon Chase and Massachusetts Senator Charles Sumner. Why did he not run in either election (I've read that he had major disagreements with Fillmore as President and personally regretted not pushing more to be VP in 1848, but I can't find much info on 1856)? If he did run, would he have been nominated by either party or would they have gone with their OTL picks? And if he had been nominated, who might've been his VP and could he have won against Pierce/Buchanan? Feel free to give map predictions and whatelse to further explain your answer because I have an idea for a Timeline that involves this scenario.
