Clinton’s cackle may give opponents the last laugh

They call it the Clinton cackle. It comes out of the blue, lasts a few seconds and leaves those who witnessed it wondering if they have missed a joke. Hillary Clinton’s deployment of the full belly laugh is the latest weapon used by the leading Democratic presidential candidate when she is being pummelled by reporters or rivals.

Friends say the cackle is her way of deflecting aggressive questioning. It may also be a sign of nervousness over Iowa, where she is now running second to Barak Obama, according to one weekend poll….

…Mrs Clinton’s friends say she has a terrific sense of humour. But her sarcastic tendencies do not go down well with Mid Western voters. So she has turned to laughter. When attacked about her many flip-flops – she voted for war in Iraq but now opposes it and she opposed universal healthcare but now wants it – she now bursts out laughing….

…The questions about her judgement are coming thick and heavy. This week there will be more as her adversary Mr Obama tours Iowa to mark the fifth anniversary of a speech he gave opposing the war in Iraq. Even Bill Clinton seems nervous about Mr Obama and said publicly last week that he was too inexperienced to run for the White House.

You can read this New York Times piece about her laugh.

It was January 2005, and Senator Hillary Rodham Clinton had just finished a solemn speech about abortion rights — urging all sides to find “common ground” on the issue and referring to abortion as “a sad, even tragic choice to many, many women.”

Stepping offstage, she took questions from reporters, and found herself being grilled about whether she was moderating her own pro-choice position. And suddenly it happened: Mrs. Clinton let loose a hearty belly laugh that lasted a few seconds. Reporters glanced at one another as if they had missed the joke.

But nothing particularly funny had occurred; it was, instead, a deployment of the Clinton Cackle.

I quit giggling when I was an early teen. It just seemed so silly to me.

Whether you call it a cackle, a screech or a combination it seems to come at inopportune times and grates on my nerves.

If she wins the presidency does she intend to laugh her way through her term?

Apparently she thinks going to war with Iran would be funny too:

Do we want a giggly middle-aged woman as our president or do we want someone who takes the world a bit seriously?
