Barack Obama used his weekly YouTube address to announce his intention to address health-care reform in the coming months, an announcement that incited Republican Senator Chuck Grassley of Iowa to make a Herculean ass of himself by raging incoherently on Twitter.

Seriously, it looks as though these rants were composed by a third grader:

"Pres Obama you got nerve while u sightseeing in Paris to tell us 'time to deliver' on health care. We still on skedul/even workinWKEND."

Are you freaking kidding?! This guy is five term United States Senator who formerly chaired the Senate Finance Committee, and he lacks the intellectual capacity to compose a coherent message using 140 characters or less on Twitter.

We've long believed that one of the best things about Twitter is that it serves to illuminate the intelligence, or lack of intelligence, of the people in the public eye who choose to use it. Say what you want about it, but Twitter does take some base literary competence to convey concise thoughts in 140 characters or less. There really is an art to it, we think.

With that said, Chuck Grassley has proven himself to be an illiterate jackass.

Big thanks to Gawker commenter/liveblogger extraordinaire for tipping us to Grassley's tweets.
