Santorum said that the Republicans did not like Gingrich as speaker because he was erratic.
I do not remember that. I do not remember anything written about Gingrich being erratic- I sort of remember some power play going on at the time.
As Speaker of the House, Gingrich would have a Number 1 Priority, Must Be Done Today initiative today and a different one tomorrow. I think that this management style is the basis of the “erratic” rap.
You can still see it in his embrace of Paul Ryan’s plan, then his rejection of it, and then his re-embrace of it.
Or in his attacks on Romney’s “vulture capitalism”.
