According to Miles’s Law, “where you stand depends on where you sit.” And so when Vice President Joe Biden hyperventilates over Republican senators’ criticism of the Obama administration’s negotiations with Iran, we must take him with a grain of salt. He used to have a seat in the Senate; now he stands behind President Obama.

Nevertheless, when the ex-senator and former Senate Foreign Relations Committee chairman condemns his successors for daring simply to point out that any substantive agreement with Iran will not become a binding treaty without Senate consent, it is hard not to chuckle. For when presidents were Republican and Senates were Democrat, Senator Biden sang a significantly different tune.
