"Still, Cruz and Christie possess a key similarity: an abundance of old-school manliness."

"Sure, one is a twangy Texan with that shit-kicking, boot-wearing thing going on (despite being a double-ivied, cosmopolitan kind of guy). The other is a Jersey bruiser, with a (much-discussed) physique reminiscent of Tony Soprano after a doughnut bender. But both are delivering a booster shot of testosterone to the GOP in a way few have managed to pull off of late...."

Writes Michelle Cottle in The Daily Beast (erasing Cruz's Hispanicity and Christie's stomach surgery).

Despite the centrality of this image to the GOP, however, precious few of its high-profile players now are apt salesmen for the manly brand....

As for the current team ... Mitt Romney: too much of a doofus. Paul Ryan: ditto, despite the washboard abs. Eric Cantor: too twitchy (manly men do not visibly vibrate with nervous energy). Marco Rubio: too boyish. Jeb Bush: too soft and measured. With his retro Mad Men groove, John Boehner has the potential to be a Don Draper kind of manly man, but he’s too darn weepy.

ADDED: I looked up "shit-kicking" in the (unlinkable) Oxford English Dictionary. It means, "In early use: worthless, contemptible. Later: designating or characteristic of an unsophisticated person from a rural area; (also) tough, belligerent; cf."

How does that relate in any way to Cruz?
