Former Senate candidate Christine O'Donnell (R-Del.) will not be the opening speaker for former Alaska Gov. Sarah Palin (R) after all.

The Des Moines Register reported Tuesday morning that O'Donnell was invited to speak at an Iowa Tea Party event that Palin is headlining, but that she was soon dropped from the speaking list.

After some Tea Partiers complained about her inclusion, O'Donnell was dropped.

Tea Party of America Co-Founder Charlie Gruschow told The Wall Street Journal that the group withdrew O’Donnell after receiving numerous "emails from a lot of Tea Party folks that were very disappointed that she would be speaking."

Palin endorsed O'Donnell in her 2010 campaign, when she shocked many with her primary win over then-Rep. Michael Castle (R-Del.). She went on to lose the general election by a wide margin after a series of campaign missteps, the most famous of which involved a video of her admitting she had dabbled in witchcraft and her campaign's pushback with an ad that closed the words, "I'm not a witch."

Palin is still publicly uncommitted about whether she will run for president. O'Donnell is on tour in support of her new memoir.
