to varying degrees, before the following year's Voting Rights Act outlawed them entirely. The five Southern states that voted for Goldwater swung over dramatically to support him. For instance, in Mississippi, where Democrat Franklin D. Roosevelt had won 97% of the popular vote in 1936, Goldwater won 87% of the vote. Of these states, Louisiana had been the only state where a Republican had won even once since Reconstruction. Mississippi, Alabama, and South Carolina had not voted Republican in any presidential election since Reconstruction, whilst Georgia had never voted Republican even during Reconstruction (thus making Goldwater the first Republican to ever carry Georgia). The 1964 election was a major transition point for the South, and an important step in the process by which the Democrats' former "Solid South" became a Republican bastion. Nonetheless, Johnson still managed to eke out a bare popular majority of 51–49% (6.307 to 5.993 million) in the eleven former Confederate states. Conversely, Johnson was the first Democrat ever to carry the state of Vermont in a presidential election, and only the second Democrat, after Woodrow Wilson in 1912, when the Republican Party was divided, to carry Maine in the twentieth century. Maine and Vermont had been the only states that FDR had failed to carry during any of his four successful presidential bids. Around twenty percent of the people who had voted for Nixon in the 1960 election switched their support to Johnson. Of the 3,126 counties/districts/independent cities making returns, Johnson won in 2,275 (72.77%), while Goldwater carried 826 (26.42%). Unpledged electors carried six counties in Alabama (0.19%). The Johnson landslide defeated many conservative Republican congressmen, giving him a majority that could overcome the conservative coalition. This is the first election to have the participation of the District of Columbia, under the 23rd Amendment to the US Constitution. The Johnson campaign broke two American election records previously held by Franklin Roosevelt: the most Electoral College votes won by a major-party candidate running for the White House for the first time (with 486 to the 472 won by Roosevelt in 1932); and the largest share of the popular vote under the current Democratic/Republican competition (Roosevelt won 60.8% nationwide, Johnson 61.1%). This first-time electoral count was exceeded when Ronald Reagan won 489 votes in 1980. Johnson retains the highest percentage of the popular vote, as of the 2020 presidential election. Johnson was the first Southern president since Andrew
