Marc Ambinder may be on Glenn Greenwald’s shitlist for playing faithful “stenographer” to the Obama administration over the state secrets issue–I think I agree with Glenn here–but Marc has regained my trust with a beautiful reconstruction of George Will’s most recent argument:
P1: John McCain enjoyed being bipartisan in the past.
P2: [All people who enjoy things in the past will want to continue doing them in the future.]
C1: Therefore John McCain wanted to continue being bipartisan.
P3: John McCain did not continue being bipartisan.
P4: [Only recklessness by House Democrats could cause John McCain not to be bipartisan.]
C2: Therefore House Democrats are reckless.
Premise-conclusion form can be useful for analysis, but where it really shines is as a tool of satire.
