Voting rights in the US have expanded over time. Originally only granted to wealthy white males, the 15th Amendment gave African Americans the right to vote after the Civil War. Women gained suffrage through the 19th Amendment in 1920 after decades of lobbying. The 26th Amendment lowered the voting age to 18. However, voter turnout remains lower in the US than other democracies due to issues like lack of interest, obstacles to voting, and complex registration. Voters are typically more educated, wealthy, older individuals who have voted before. Some groups like felons and non-citizens cannot vote. Voters are influenced by background, party loyalty, issues, candidates' images, and political propaganda.
