“A new Marquette Law School Poll national survey finds 54 percent of likely voters saying they will vote for a Democrat in congressional elections in November, while 41 percent say they will vote for a Republican. In July, the Democratic advantage was 51 percent to 45 percent… Among all registered voters, Democrats hold a 50 to 42 percent advantage over Republicans, a larger margin than the 46 to 44 percent gap in July’s Marquette Law School Poll,” says the pollster in their release.
