Early voting has surged in some states, analysts reported Friday, foreshadowing a possible turnout of between 45 and 50 percent of eligible voters in November's midterm elections. That would be the highest figure since at least 1970, when turnout hit 47 percent, and could possibly be the highest since 1966, when turnout was 49 percent. This is a significant turnaround from the 2014 midterms, when just 36 percent of eligible voters cast ballots, the worst showing since World War II. Turnout was also way up in primary elections earlier this year; about 37 million people participated in House primaries, compared to 24 million four years ago.
