Go Frothy

Santorum just compared himself to a turtle...which should make you wonder about "Senator Man on Dog" but something interesting...if rather off-putting...is oozing forth:

...the four-day results don’t reflect just how quickly momentum is shifting in a race that has remained highly fluid for months. If the final two days of polling are considered separately, Santorum rises to second place, with 21 percent, pushing Paul to third, at 18 percent. Romney remains the same, at 24 percent.

Why is everything about Santorum a double-entendre?
