After 1912, the Republican Party began to undergo an ideological shift to the right. Following the Civil Rights Act of 1964 and the Voting Rights Act of 1965, the party's core base shifted, with Southern states becoming more reliably Republican in presidential politics. After the Supreme Court's 1973 decision in "Roe v. Wade", the Republican Party opposed abortion in its party platform and grew its support among evangelicals. Its 21st-century ideology is American conservatism, which incorporates both social conservatism and fiscal conservatism. The GOP supports lower taxes, free-market capitalism, restrictions on immigration, increased military spending, gun rights, restrictions on abortion, deregulation, and restrictions on labor unions. The party's voter base in the 21st century largely includes white men, people living in rural areas, members of the Silent Generation, people without a college degree, and evangelical Christians. Its most recent presidential nominee was Donald Trump, and most Republicans are generally supportive of his opinions and actions.
