The presence of north-to-south flowing rivers in the US affected its development by creating a economic bond between the North and the South, which some believe stemmed the onset of the Civil War until the creation of the railroad. Take Chicago, for example. Chicago existed as an agricultural hub where farm goods from the Midwest would go before making their way to larger markets. Before the Civil War, those goods traveled South down the Ohio and Mississippi Rivers and then were sold at New Orleans. This led the Western half of the US to look warily at Civil War because it would directly impact their ability to conduct trade. However, in the 1850s and 60s, Northern manufacturers began building railroads from Northern cities to Chicago, which artificially redirected the flow of farm goods to the East. Now, free from fearing an end of trade, Western politicians were more likely to approve of the Civil War.
Landslide victories do not guarantee that Congress will be of the same party and therefore can prevent continued success by the President.
These presidents were reelected due to the trust Americans had in them to get the country through a tough time. FDR--Great Depression, LBJ--assassination of JFK, Nixon--Vietnam/activism, and Reagan--recession. However, Congress was not in their favor to continue the policies they had been using in their first terms. On that note, these were all 2nd term (LBJ was technically first election but had served two years already) elections where the president had gained the approval of the people.
All faced increased adversity as well after the landslide victory. FDR--recession and WWII begins, LBJ--entry into Vietnam, Nixon--Watergate, and Reagan--stock market crash.
