to right a wrong

[jctgf]

McCain had to ground Fiorina after she said Palin was not qualified to lead a major corporation, then tried to right her wrong by admitting McCain wasn't qualified either – or Obama or his running mate Joe Biden, for that matter.

hi,
I heard this expression for the first time when watching a movie and I thought it was a Hollywood slang. now I came across it again in an article from an influent newspaper. is it good English, please? can I use it unconcernedly?
thanks.

It is a recognised, if rather old-fashioned, phrase.

What do you mean by "use it unconcernedly"?

thanks.
"unconcernedly" was the best word I could find in the dictionary meaning "in a non-concerned way". which word should I have used, please?
thanks.

I think you mean "casually."

Actually, with the political situation in America the way it is, there are many politicians using the phrase "righting a wrong."

You will hear it again . . .

hi,
i had never noticed that 'casually' may fit the idea that i am trying to express. i am trying to improve my vocabulary. so, if i wasn't allowed to use 'casually', which word should i use, please?
thanks.
sorry for the non capitalized 'i'.
