Los Angeles — “Gravitas,” that quality defined as credible expression of knowledge and purpose, was the watchword of the national security discussion. Who would have more of this essential quality on “Day One,” and who has displayed more in his/her political actions to date? Both candidates have skillfully made their practiced debating points on the October 2002 Congressional Resolution, which Hillary voted for, and which authorized military action against Iraq. Hillary did her best with her “If I had known then what I know now” line, and there is no sign of substantial disadvantage to her or advantage to Obama. Who has more “gravitas” is a question left unresolved.
