Lieberman endorses McCain; McCain uses awful new word

"I was a little reluctant to ask him, because I didn't want him to do something that may cause any harm to his political future," McCain told reporters in Concord. "I felt it would be impactful in the election otherwise I wouldn't ask for it." (NBC First Read)

Ugh, impactful? That is even worse than the use of "impact" as a verb. Please do not use this word, English speakers.
