Final answer:
Online voter registration is the only option listed that does not make it difficult for citizens to register to vote. It is intended to expedite the process and increase voter turnout, but some states are cautious due to security and election fraud concerns. Other hindrances to voter registration include inadequate resources, clerical mistakes, and restrictive new laws on registration drives.
Step-by-step explanation:
All of the following make it difficult for a citizen to register to vote except online voter registration. Online voter registration is designed to make the voter registration process faster and more accessible to citizens. While some states have implemented this to boost voter turnout, others have concerns about potential election fraud and security, which has led to hesitancy in adopting online systems. However, in places where it has been implemented, like Florida in 2015, it was done so with substantial citizen support, despite security concerns. As technology advances, online registration is expected to become easier and safer, potentially increasing the pool of registered voters.
Other factors that make registration difficult include inadequate resources, clerical errors, failures to notify registrants of issues with their forms, and new restrictions on voter registration drives. These can lead to a significant drop in newly registered voters, particularly among minority groups. States may also have residency requirements or ask further questions on the registration form that can pose barriers to some prospective voters.
