Daniel Henninger asks some very good questions about what the leading Democratic contenders--Senators or former Senators all--think of executive power. We kinda know, as he notes, that HRC wouldnt settle for a domestic presidency any less powerful than WJCs. But what about foreign affairs? We dont enjoy the luxury of spending a long time settling that question after January 20th. Folks interested in the presidency should spend some time defending the prerogatives of that office from their party colleagues and partisan supporters. If they are unwilling or unable to do so, they dont deserve to hold the office.
