"The latest Rasmussen Reports national telephone and online survey finds that 60% of Likely Democratic Voters say they are more likely to let others know how they intend to vote this year compared to previous congressional elections. This compares to 49% of Republicans and 40% of voters not affiliated with either major political party. (To see survey question wording, click here.)
In August 2016, 52% of Democrats were more likely to let others know how they intended to vote in the upcoming presidential election, compared to 46% of Republicans and 34% of unaffiliated voters. Some analysts before and after Donald Trump's upset victory suggested that most pollsters missed his hidden support among voters fearful of criticism who were unwilling to say where they stood.
Similarly when asked now about family, friends and co-workers, 60% of Democrats say they are also more likely to tell others how they intend to vote, but only 46% of Republicans and 45% of unaffiliated voters agree." Rasmussen
The Left does not like "Rasmussen Reports" as a polling company, claiming that it is a Republican shill. The cited Wiki article on the company indicates that it has had quite a good record on predictive analysis based on its polling.
This article highlights the differential response between conservatives and the Democrats when asked questions as to how they will vote. The poll indicates that "red" Americans are less willing to tell pollsters what they will do.
I think that is true and that there may be a surprise waiting for the Democrats (including Nancy Pelosi) on Tuesday evening. pl
