The Federal Election Commission rarely enforces laws against coordination between political campaigns and groups making independent expenditures for and against candidates. Meanwhile, outside spending is exploding to the point that in some races, independent expenditures dwarf money spent by the candidates.

As a result, each election cycle brings more actions that raise suspicions of campaigns and outside groups coordinating their work. In Iowa’s U.S. Senate race, Joni Ernst’s campaign magically knew exactly when to launch a very small ad buy to maximal effect–on the same day an outside group released a months-old unflattering video of Bruce Braley. Later on, a super PAC came into existence solely to run a $1 million television commercial targeting Braley, and that super PAC just happened to be headquartered in the same office as a senior consultant for Ernst’s campaign.

CNN’s Chris Moody reported today on a newly uncovered, brazen scheme to share information between campaigns and political advocacy groups. Click through to read his whole piece about Twitter accounts that communicated polling data from competitive U.S. House races.

At least two outside groups and a Republican campaign committee had access to the information posted to the accounts, according to the source. They include American Crossroads, the super PAC founded by Karl Rove; American Action Network, a nonprofit advocacy group, and the National Republican Congressional Committee, which is the campaign arm for the House GOP. […]

The accounts that CNN reviewed were active in the months ahead of this month’s election, which gave Republicans their largest majority in the House since World War II and control of the Senate. They were live until Nov. 3 but deleted minutes after CNN contacted the NRCC with questions. […]

The tweets captured by screenshots stretched back to July, but the groups have communicated in this manner for four years, the source said. Staffers for each group deleted individual tweets every few months, so only the past few months of data were available when CNN first viewed the Twitter accounts.

Deleting online content minutes after a journalist starts asking questions sends a strong signal that these operatives knew they were doing something shady. Moreover, Philip Bump noticed that the American Action Network was one of the biggest outside spenders in the Congressional race in Florida’s 26th district. That race was the apparent focus of at least one now-deleted tweet containing polling data, which showed a very close race in FL-26.
