Try to give a little more info in your posts next time!
What this is:
It's actually an online (flash) fighting game in the style of "Mortal Kombat", based on the political candidates in the US 2008 election.
I have to say it's extremely well done, and has a fair bit of humour in it as well (tip: play hillary and use your distance attack to see who shows up for a cameo).
It's quite violent, like all of these Mortal Kombat games, and so may be not suitable for children.
