Apparently using old sayings and metaphors can cause great controversy on the campaign trail:
[Sen. John McCain] smirked as he heard the former Massachusetts governor’s assertion that McCain wanted to allow illegal immigrants to remain permanently in the United States.
Asked how he intended to respond, the Arizona Republican said: “Never get into a wrestling match with a pig. You both get dirty — and the pig likes it.”
The back-of-the-bus compartment in which McCain was holding forth went silent for several seconds. Finally, a reporter asked: was McCain comparing Romney to a pig? McCain laughed and paused as he formulated his response: “That was a general philosophical approach to American politics.”
Screams of outrage that McCain called Romney a “pig” in 3… 2… 1…
Screams of outrage from Romney haters that McCain has insulted the consistent positions held by pigs in 3… 2… 1…
