Perhaps there are now 60 Senators to override a veto. Sixty Senators who realize now that a big mistake needs correction before this November’s elections. Maybe not; but it is possible, IMHO.
At present, you’d need 13 Democrats to cross over, and while there are certainly a handful who’d consider it, there are too many left-wingers in states where they have no effective opposition.
The Senate needs 67 votes (2/3 majority) to override a veto.
