Sure it's possible, and that point was raised by George Will, who is not known to be a flaming liberal.

Contrast that with the toe-the-party-line-no-matter-what mentality so common among liberals, regardless of how obviously crooked Hillary is. Political power, no matter how dishonest.
Speaking of honesty/dishonesty, at least the HuffPo makes no secret of its bias, ending every article I've seen on Trump with the following:
"Editor’s note: Donald Trump regularly incites political violence and is a serial liar, rampant xenophobe, racist, misogynist and birther who has repeatedly pledged to ban all Muslims ― 1.6 billion members of an entire religion ― from entering the U.S"

The NY Times and the Washington Post could well follow the HuffPo's example, but of course they won't.
