One pro-democracy group says it's their "most popular campaign of the year," generating nearly 100,000 emails. But lawmakers are still working out the details for a potential ban, leading to frustration on Capitol Hill. More than 7 in 10 likely voters believe members of Congress should not be allowed to buy or sell individual stocks while in office, according to new poll shared with Insider.The Data for Progress poll indicates that 70% of respondents want new federal legislation to ban the practice, while 68% said such a ban should extend to lawmakers' spouses.And 49% of respondents said they were more likely to support a candidate who backs a stock trading ban, including 50% of Republicans and 45% of Democrats."It's not just about level of support, but it's about an enthusiasm that people have for this issue," said Brett Edkins, the managing director for policy and political affairs at Stand Up America, a left-of-center governmental reform nonprofit that commissioned the poll.
