From Gail Collins’s op-ed column in the NYT yesterday, “A Ted Cruz On Every Corner”, about recent looniness from Texas lawmakers:
The old center-right standard-bearer, Lt. Gov. David Dewhurst, is desperately trying to wipe out his reputation as a mainstream politician while he runs for re-election.
“I don’t know about you, but Barack Obama ought to be impeached,” he told a Tea Party gathering recently, with more fervor for the cause than for grammatical construction.
Collins doesn’t explain her objection, but I’m guessing she thinks that Dewhurst should have said:
“I don’t know about you, but I think Barack Obama ought to be impeached.”
(supplying the source of the opinion in the second clause). So she’s treating this case as (roughly) parallel to the truncation of as far as X goes / is concerned to just as far as, which has been widely reviled (for reasons I don’t fully understand).
