I noticed that, also. Goldwyn and a lot of others, including me, make that kind of joke purposely.
And the Post writer being quoted wrote, "Alexandra Petri discussed 'the trouble with Joe' and took the VP to task for 'periodically alarming outbursts.'
I think she meant "...for periodic, alarming outbursts." The alarms aren't periodic, as she wrote; the outbursts are.
I missed the bit about periodically alarming outbursts. Very good catch on your part.
Their thinking sucks, their writing sucks... everything about liberalism sucks and sucks and sucks.
It just never stops.
