evidence: Graham’s press office sent us a Dec. 10 letter from the CBO. The agency did say the deficit would go up by $3 trillion, but that was for, as they put it, "a modified version of H.R. 5376, the Build Back Better Act." [...] To unpack this — just a little bit — Congress passed a budget resolution that set a ceiling on how much, if any, a bill like Build Back Better could add to the deficit. When the CBO scored the bill as adding $158 billion to the deficit, the Democrats were well below the ceiling they had set. (Technically, the CBO said the bill added $365 billion, but it also figured that IRS enforcement would help offset that by $207 billion.) [...] Graham said the CBO predicted the Build Back Better Act would add $3 trillion to deficits over 10 years.
