(CNN) - A fifth-generation Wyomingite, a family woman of conservative principles, and a member of a new generation of leaders.
That's the picture Liz Cheney's campaign paints in its first television ad, which will debut across the Cowboy State on Thursday.
"I'll fight hard, I'll fight smart, and I'll get the job done," says Cheney, the eldest daughter of former vice president Dick Cheney, who served for a decade as a congressman from Wyoming.
The former State Department official and Fox News contributor announced her candidacy in mid-July, challenging incumbent Republican Sen. Mike Enzi. A three-term senator, Enzi was caught off guard by Cheney's announcement, telling reporters at the time that she had previously promised not to not enter the Republican primary if he sought re-election.
Since then, Cheney's campaign has torn into the 69-year old senior senator, calling his age into question.
"I'm running for the United States Senate because it's time for a new generation of leaders to step up to the plate," she says in the new ad.
For its part, the Enzi campaign and its affiliates have questioned Cheney's Wyoming roots.
Some have accused the Wisconsin-born, Virginia-raised lawyer of being a carpetbagger, and the social-conservative PAC American Principles Fund called her "wrong for Wyoming" in television ads this fall.
That charge is one Cheney is actively combating. The new ad features childhood photos from her time in Wyoming, a family tree of famous Wyomingites dating back to 1852, and lots of air time for her husband and five children, with whom she moved to Jackson Hole last year.
The primary will take place next February, and the general election, next November.

She is a carpetbagger. When was the last time before this campaign that she spent more than a year or so in the state?
I thought Dick only left Texas for Wyoming because we were not supposed to have a president and Vice President from the same state. No more Cheney's.
Now, this is a woman of intelligence and integrity.
theres a new kid in town and she is bringing good change
Give me a brake !
She still thinks climate change is a conspiracy done with photoshop .
And if Wyoming is dumb enough to elect her, she'll just be another Dick puppet.
Right – sh'e spent the majority of her life in Virginia.
You are a mull like your father.Any attempt by you or family to stage a come back to Washington will fail. You family had already erased his name from the good book of America rulers. All what George Bush and father did to America will linger on in the mind of American people born and yet unborn.
Don't change a single thing Guns Over People tea potty wingnuts. Stand for your principles! Everything is fine when you are
taken over by ADolph Cheney's slimy family.
So the rich little "twig" girl was able to go with her trigger happy daddy on vacation to Wyoming but it was not good enough until last year to live in year round.
