In 2010, Grimes announced her candidacy for the office of Secretary of State of Kentucky, left open by term-limited incumbent Republican
Trey Grayson. When Grayson resigned to accept a position at the
Harvard Institute of Politics, Governor
Steve Beshear appointed
Bowling Green mayor
Elaine Walker over Grimes to fill the rest of Grayson's term in office. Despite this, Grimes stayed in the race and defeated Walker by a double-digit margin in the May primary. She became well known through commercials that showed her elderly grandmothers. Grimes defeated Johnson with over 60% of the vote. She received a higher percentage of the vote than any other
Kentucky statewide Democratic candidate during the 2011 elections. Her term as Secretary of State began on January 2, 2012. In 2012, Grimes visited the Middle East to observe the voting process of overseas military personnel. This experience led her to become an advocate of an improved voting process for the U.S. military. Grimes's recommendations received bipartisan support in the Kentucky General Assembly and were signed into law in April 2013. The Kentucky Military Heroes Voting Initiative law allows military members and other covered voters to register to vote and update their registration online, ensures that military voters have sufficient time to vote in special elections, and extends existing protections to state and local elections and National Guard members. On March 14, 2016, Grimes launched the online voter registration system GoVoteKY.com. A statewide voter registration drive she led during the 2016 presidential election resulted in more than 100,000 new voters. Grimes continues to push for introducing in-person early voting in Kentucky elections. Kentucky is among a handful of states which do not allow voters to cast ballots in person without an excuse before election day. In November 2017, Grimes announced the formation of a task force for legalizing the
medical use of cannabis in Kentucky. In January 2018, House Bill 166 was introduced which incorporated the recommendations of the task force. In March 2018, Grimes coauthored an op-ed with Medal of Honor recipient
Dakota Meyer calling for passage of the bill. The bill stalled, however, which Grimes blamed on Republican leadership "holding the bill hostage". Grimes is an advocate for the restoration of voting rights for Kentucky's non-violent felons who have served their sentences. Kentucky remains one of three states which does not automatically restore voting rights to felons who have completed their sentences. Grimes has been a proponent of legislation and initiatives to aid individuals with disabilities, including working with Kentucky agencies to help educate disabled voters about their rights at the ballot box and advocating for a law that improves communication between law enforcement and the more than 700,000 Kentuckians who are deaf or hard of hearing. Grimes has been criticized for controlling the Secretary of State office and the
State Board of Elections's day-to-day functions, among other controversies. Her extensive oversight, including have representatives from the SOS office present during interviews of the SBE members making claims in the investigations of the
controversies, has been described as intimidating to those in the SBE. ==2014 U.S. Senate campaign==
