You forgot about the two pocket vetoes Bush attempted while Congress was not in session -- those were considered to be enacted because he didn't return the legislation. What I would like to know is how many Bush considered vetoing but found out he would be overridden if he did veto them. I can remember a few vetoes being threatened but then the law was enacted. I would guess they were not vetoed because Bush knew he would lose.
He did not veto any bills for his first five years in office. Here is what the
Christian Science Monitor, "On many major bills that Bush has signed - No Child Left Behind and tax relief, for example - the veto was never a consideration because the White House itself had proposed the legislation. Yet on dozens of other bills, the president has become a rubber stamp for a spendthrift Congress, betraying his campaign image as a fiscal conservative, critics say." (

Maybe the bills he did NOT veto should be considered as much as the few he did?
