Sarah Palin will be walking into the proverbial lion’s den when she guest hosts Tuesday’s Today show, as the NBC morning program’s hosts, reporters and guests have repeatedly trashed the one-time Vice Presidential candidate. While the former Alaska governor was treated to jovial jabs from the cast when she called into Monday’s Today show, she’s been subjected to much harsher attacks over the past four years.

On the show Palin has been blamed for the shooting of Democratic Congresswoman Gabrielle Giffords, denounced as a political liability for the GOP, been called a “Nazi” by journalist/stalker Joe McGinnis, and has seen herself and family become the object of rampant speculation and crude mockery.

The following are some of the worst instances of Palin bashing that were aired on NBC’s Today show:

With the help of the MRC's talented Bob Parks, the Culture and Media Institute produced a video based on its

March is Women's History Month, in which we acknowledge the accomplishments and contributions of women in history and in society today.

But for a select group of women - conservative women - their accomplishments and contributions are rarely celebrated but often demeaned and mocked in sexist - and crassly sexual - ways.

The Culture & Media Insitute looked back at what the media had to say over the past year about some of today's most prominent conservative women, including Michelle Malkin, Elisabeth Hasselbeck, Sarah Palin and Liz Cheney, and compiled a list of the 10 worst attacks on these women who dare to speak out in favor of conservative values.

Much of the criticism was the worst sort of misogyny with a dose of violence and disgusting adolescent sex references thrown in for good measure. The media outlets in question ranged from Playboy magazine to MSNBC to Sirius XM radio and included comments from both men and women.

The message that rang through loud and clear was that perspectives from conservative women were not appreciated or welcomed, and if a woman stepped out of line, she deserved whatever treatment she received.

Tiger Woods' "transgressions" sparked conversations about why men cheat but it took a comedian to pinpoint the basic reason - lack of character.

Comedian Chuck Nice appeared on the "All Guy Panel" during the fourth hour of Thursday morning's "Today" and blasted men who engage in extramarital affairs.

"I've said this before and I will say it again. And no one wants to accept this as an answer, but here is the reason why men cheat. It is a failure of character. That is it," Nice exclaimed.

"End of story. It's a failure of character," he continued. "A man who has the strong, spiritual conviction to say that although I want to do this, I will rely upon a higher power to make sure and strengthen me so that I am able to stand for my vows is the man who will not cheat. Now, that's the end of it."

You might consider that speculating about a candidate's sexuality would be off limits in the responsible media. Yet that's just what happened on MSNBC this morning.

Chuck Nice is a comedian, after all, so perhaps his comments should be taken with a grain of salt. Even so, the panelist on today's "Morning Joe" twice ventured into territory that would normally be considered verboten.

Brad Luna of the Human Rights Campaign was the phone guest, discussing the presidential candidates forum that his homosexual-rights group conducted yesterday. Without endorsing Hillary, he did single her out for favorable mention.

HUMAN RIGHTS CAMPAIGN DIRECTOR OF MEDIA RELATIONS BRAD LUNA: Hillary does have a certain comfortableness with the issues and with our community. Obviously this is somebody you can tell has had a lot of contact discussing the issues, has thought about them for a number of years, and I do think that her sincerity and her genuineness came across last night.

MORNING JOE PANELIST CHUCK NICE: Are you saying that Hillary Clinton is bi-curious?
