These charts are from a new Pew Research Center's latest survey. It was done between January 10th and 15th of a random national sample of 1,503 voters, with a margin of error of 2.9 points.
It shows the Democrats with a 14 point advantage (53% to 39%) when voters were asked which party's candidate they would vote for in their own congressional district. That's significant. But preference and actual voting results do not always mean the same. Democrats have a real opportunity in 2018 -- but only if they work hard and get their voters to the polls.
The second chart shows another Democratic advantage. Democrats are more excited about voting this year than Republicans by 11 points (69% to 58%). That's different than most recent elections, where Republicans held the advantage in enthusiasm.
