Trump's slight lead is probably less important than the trend line, which over the last couple of weeks shows him gaining and her losing support. Each is popular with their own party members, but Trump is ahead of Clinton among independents with 49% to her 29%. Marriage also makes a difference:
Among women, those who are unmarried make up the core of her support, 73% of unmarried women back Clinton compared with just 36% of married women. Among men, no such marriage gap emerges, as both unmarried and married men favor Trump.
