Good list. Obama's margin in PA and CO in 08 still amazes me. CO was solid red until 08. His PA margin is the best by any presidential candidate since Nixon 1972.
Bush's strong 5 point margin in FL in 04 was due to his strength with Latinos in south Florida (he lost Miami-Dade county by just 7 points, compared to Trump losing it by 30), and Tampa and Orlando.
Correction: Bush 04 won Indiana by 21 points.
I would also add Trump's 19% margin in Missouri, which is stunning given that the state was historically a swing state. HW Bush won it by just 4 points, Bill Clinton won it twice, W Bush won it by 3 and 7 points, McCain barely won it by 0.1%, and Romney won it by 9 points. Trump's margins in MO and IN indicated his strength with working class whites in the midwest and border South.
