Final answer:
The most significant election concern among voters was health care, greatly influenced by rising health care costs and the impact of the COVID-19 pandemic. While immigration and the economy were also important, health care remained a prevailing concern, shaping voting decisions.
Step-by-step explanation:
The issue that garnered the most concern among voters during the election was health care. This is indicated by various polls and surveys conducted around election periods. For example, a CNBC article from November 8, 2018, reports that health care topped the economy as the biggest issue for voters at that time. This was attributed to rising health care costs and debates around health insurance access and affordability. Additionally, during the COVID-19 pandemic, health care became an even more pressing concern, influencing voting behavior significantly.
Voters are typically less focused on foreign policy unless there is a crisis, as domestic issues such as the economy, health care, and crime resonate more strongly with them. Immigration policies also became a significant concern, especially in border states where there is a perception of a rising threat from illegal immigration. Nonetheless, data from the 2020 U.S. presidential election indicates that the handling of the COVID-19 pandemic was also a critical factor, though health care, the economy, and racial inequality were more frequently cited as top issues.
