Final answer:
The Declaration of Independence's principle of republican government, where citizens elect their representatives, is reflected in the U.S. election process, with its emphasis on liberty and equality.
Step-by-step explanation:
The founding principle from the Declaration of Independence reflected in the election process is the concept of republican government, where the people elect their leaders. This concept embodies the notion that government should be of the people, by the people, for the people, as famously stated by Abraham Lincoln. Although initially, the right to vote was limited to property holders, aligning with a bias toward the elite, the evolution of American democracy has extended suffrage rights, embracing a broader definition of republicanism. Over time, the inclusion of larger portions of the population in the election process has also mirrored the Enlightenment ideals of liberty and equality that heavily influenced the Founding Fathers. Voter participation remains a vital aspect of American politics, ensuring the representation of citizens' interests in government.
