💢 Voter surveys can be a source of encouragement for Democrats.
Anthony Zorker, BBC correspondent in Washington.
Now that we have a chance to look at the wave of data from voter surveys in the midterm elections, one point is worth noting.
This national survey, taken from actual voters, has so far succeeded in reflecting the trends we have seen in major public opinion polls in recent months.
The economy is the main concern of voters. Worries of political corruption are also among their main concerns.
The level of satisfaction with Donald Trump's performance, with 38% in favor and 61% in opposition, is clearly in an unfavorable state.
If Democrats were worried that the latest polls might be too far from the truth, these findings could give them some encouragement, at least for now.
