No longer present. When this page was last checked, on September 7, 2026, this guidance was not found. The finding remains on the ledger and the archived evidence below is preserved — guidance taken down after drawing notice is itself part of the record.

The page is a media-buy guidance document, not a standard press kit or voter persuasion page. It specifies exact audience segments, channels (mail, YouTube, CTV), timing ('Starting immediately'), and message themes as directives, clearly addressed to an outside group that will run paid advertising. The presence of downloadable ad assets and a promise of further updates confirms its function as red-boxing.

Quoted evidence — verbatim spans from the page

  • likely Democratic primary voters who are Democrats or Unenrolled districtwide, who have voted in at least 2 of the 4 past primaries, need to read about Dan Koh that:
    Segmented audience paired with a directive about what they 'need to read' — a media-buy instruction for an outside spender.
  • voters in MA-6 need to see the following message on YouTube (all voters of all ages and genders) and CTV (prioritizing Democrats and Unenrolled voters age 35+ who have voted in at least 2/4 primaries, expanding beyond that if budget permits):
    Channel, geography, and audience targeting specified as an instruction — classic red-boxing for paid media.
  • MORE UPDATES WILL BE POSTED HERE.
    Dated update cadence implying ongoing instruction to an outside group.
  • DOWNLOAD IMAGES / DOWNLOAD VIDEO / DOWNLOAD CLIPS
    Ad-asset provisioning for use in paid communications.

Starting immediately through Election Day, likely Democratic primary voters who are Democrats or Unenrolled districtwide, who have voted in at least 2 of the 4 past primaries, need to read about Dan Koh that:

Dan Koh is an Andover native, a descendant of Korean and Lebanese immigrants, and a fighter with the experience we need to take on Trump.


From the Biden White House, to Mayor Marty Walsh’s City Hall, to the Andover Select Board — Dan has devoted his career to making government work for the people, not special interests. On the Select Board he helped put Andover on a healthy financial path. As Marty Walsh’s Chief of Staff, he oversaw record job growth and affordable housing expansion. As a senior advisor in Biden’s White House, Dan lowered prescription drug costs, raised the minimum wage, and fought back against Trump-era policies that hurt workers.

And after seeing firsthand Trump’s abuse of power, he’s ready to go to Congress to: 

Stop Trump’s destruction of our Democracy

Lower costs and make healthcare affordable for everyone

Abolish Trump’s ICE

End Trump’s illegal tariffs and illegal wars

End Trump’s tax breaks to the ultra-wealthy that are rigging the system against working people

Protect our rights, including the right to abortion

And that’s why he’s proudly endorsed by President Joe Biden, Vice President Kamala Harris, Secretary Pete Buttigieg, and more than 80+ local elected officials, labor unions, and progressive groups. Dan is also rejecting corporate PAC money.

Starting immediately, voters in MA-6 need to see the following message on YouTube (all voters of all ages and genders) and CTV (prioritizing Democrats and Unenrolled voters age 35+ who have voted in at least 2/4 primaries, expanding beyond that if budget permits):

As a senior advisor in the Biden White House, Dan Koh helped fix the damage from Trump’s first term. Now he’s running for Congress to take on Washington corruption. That’s why he doesn’t accept any corporate PAC money and went above and beyond what was required of him when he was at the White House by divesting from all his stocks to avoid any possible conflicts of interest. In Congress, Dan Koh will defend democracy and ban insider trading by politicians.
