List four elections that might be considered "critical" or "realigning." explain why.

The answers are; [1] Andrew Jackson founded the Modern American Political Party [aka Democratic Party]

[2] Abraham Lincoln started the civil war, leading to a sixty-year strive for republicans in the government. 

[3] Franklin Roosevelt created the New Deal coalition. Democratic Party gained support from people that were involved with the New Deal plan.

[4] Nixon created Republican dominance. House of Representatives has a Republican majority now.

Hope this helped! :)
