Even their sentence structure is biased.
That sentence should have listed the results in the same order:
Fifty-seven percent of Republican primary voters view Gingrich as a conservative, 28 percent see him as a moderate and 10 percent believe he’s liberal.
By comparison, only 29 percent of them view Romney as a conservative, a whopping 53 percent see him as a moderate and 11 percent believe he’s a liberal.
I noticed that too.
They also used the words first choice leaving a positive comment of Romney being in 2nd place.
