Donald Trump was absent from Fox News’ Republican debate Thursday night, presiding at his own event a seven minutes’ drive away featuring cameo appearances by the two previous Iowa Republican caucus winners exiled now to the undercard debate, Mike Huckabee and Rick Santorum. But the issue Trump raised to high-decibel level at his announcement last June was front and center at the main event: Immigration.

It was raised midway through the debate by the moderator Trump cited as the reason for his non-participation, Megyn Kelly. She ran videotape montages of previous comments on the issue by Marco Rubio and Ted Cruz, and asked them to explain the discrepancies between what they said then and their positions now. She could have played a similar montage for Trump if he had shown up.
