EL PASO, Texas (CNN) – For the second election night in a row, Hillary Clinton failed to acknowledge or congratulate Barack Obama after he won the day in dominating fashion.
On Tuesday in El Paso, hours after Virginia had been called for Obama, she stuck to her “Texas campaign kickoff” message and did not stray from an energetic, Lone Star-themed stump speech. She did mention Obama by name, only to chide his health care plan.
On Saturday night in Richmond, Virginia, Clinton spoke to a crowd of thousands at the state’s annual Jefferson-Jackson dinner, but she ignored Obama’s quartet of blowout primary and caucus wins that day as well (Obama also won the Maine caucuses the next day).
The courtesy of conceding a primary or caucus loss - and then congratulating your opponent - is by no means required. But it has become standard practice during campaign season.
Clinton congratulated Obama and John Edwards after their first and second place finishes in the Iowa caucuses. Obama returned the favor in New Hampshire, saying Clinton “did an outstanding job.” That courtesy continued through the early states.
But as the race has shifted to a delegate chase with dozens of states in play around the country, the notion of congratulating one’s opponent seems, for Clinton, to have fallen by the wayside.
