There used to be an expression that said “politics stops at the water’s edge.” Some people took it to mean that you never criticized the president when he was out of the country, but what it really meant was that, when the president was facing an international threat or challenge and trying to protect the country, that was not the time to be taking partisan potshots at him.
If we had a liberal president who was trying to impose single-payer health care, massive tax increases and crushing new business regulations, I would not with the liberal president success on any of those initiatives. In my view, they would be wrong for the country.
