Christine O'Donnell, the Tea Party candidate who memorably said she was "not a witch" in a 2010 ad, is thinking about a Senate rematch. [WATCH VIDEO]

"Number 1 is my parents' health. Lavelle can't appreciate that?" she tweeted.
The tweet was in response to a comment from Senate Minority Whip Greg Lavelle (R) in The Wilmington News Journal, urging her to make a decision now.
"Lavelle's statement that candidates can't decide to run in 2014 until I make a decision suggests he's stuck in back-room deal mindset," she tweeted.
Lavelle earned O'Donnell's ire with comments to the Wilmington paper.
"The decision to run is a big one, particularly for a United States Senate seat. There’s a lot of variables involved. But to run a serious race, or give somebody else the ability to run a serious race, you don’t [decide] in May of 2014. You do that now," he said.
Boosted by the Tea Party, O'Donnell easily won the 2010 GOP Senate primary over establishment favorite and former Rep. Mike Castle, who was seen as the stronger general election candidate.
Many believe O'Donnell's win in the primary helped prevent Republicans from winning back the Senate in 2010, in what was a landslide year for the party.
Revelations surrounding her youthful experimentation in witchcraft and a number of gaffes in debates and along the campaign trail — as well as an infamous ad in which she declared "I am not a witch" — sank her candidacy and helped Coons to win with 57 percent of the vote.
