I think he was a pretty bad President whose accomplishments were almost entirely just taking credit for Republican initiatives
The welfare reform is a very good example. It was a Republican initiative, but Clinton signed it and started to claim "I reformed the welfare".
The idea that there is any credit to be taken for Welfare reform of any of the legislative horrors of the late 1990s is the root of the problem here.
Even if they had the votes to override (which they likely wouldn't have if the leader of the party, the President, opposed), he still should have vetoed anyways like Truman did with Taft-Hartley.
