Newt Gingrich’s campaign has just sent out a memo that reveals (to no one’s surprise) a defiant determination to stay in the race until the end. If you read between the lines, it looks like he’s almost conceding tonight’s races in advance.

The memo notes that today’s contests “are big, but it’s still early,” and calls the Louisiana contest on March 24 “halftime.” Even by halftime, he asserts, the race will not be over.
