Despite spending his vacation in the summer heat of Martha's Vineyard, President Obama has declined an offer to partake in the Internet's favorite charitable wet t-shirt contest.

Obama was nominated to take the challenge Sunday by Ethel Kennedy, the widow of former Sen. Bobby Kennedy. On Facebook, the 86-year-old challenged the president to join her in the #StrikeOutALS challenge by dumping a bucket of ice water on his head.

"Welcome to Cape Cod, President Obama. I nominate you," Kennedy declared on the social media site.

The challenge has gone viral in recent weeks as Internet users have soaked themselves with ice water in support of the ALS Association, a charitable organization committed to eradicating Lou Gehrig's Disease. An alternative to the challenge - make a donation in support of the ALS Association.

It looks like President Obama will be taking the high road this time around. In a statement Wednesday, White House spokesman Eric Schultz said, "The president appreciates Mrs. Kennedy thinking of him for the challenge - though his contribution to this effort will be monetary."

Several other politicians, however, have been more than willing to join in.

Today, Louisiana Gov. Bobby Jindal accepted the challenge, posting a video to YouTube. In the video, Jindal nominated "Duck Dynasty's" Willie Robertson, Louisiana State football coach Les Miles and host of MSNBC's "Morning Joe" Joe Scarborough.

New Jersey Gov. Chris Christie was also more than willing to get drenched on the Internet. Nominating some pretty big names in his Facebook post, Christie called out "Tonight Show" host Jimmy Fallon, Facebook CEO Mark Zuckerberg and Sen. Cory Booker, D-New Jersey.

Not to be outdone, Sen. Lisa Murkowski, R-Alaska, posted a video of herself jumping into the frigid Alaskan waters in support of the ALS Association. Ditching the bucket altogether, Murkowski jumped into the 30-degree ocean from aboard a fishing boat. Her nomination? The entire United States Senate.
