Did Sarah Palin Just Announce Her Candidacy For 2012?

Sarah Palin gave a rousing speech to Tea Party members in Madison, Wisconsin this afternoon at a tax day rally. You can watch the entire speech in the clip below. 

Not only did she draw conservatives but also drew Union protesters as well who were reported to have surrounded the Tea party members during her speech. 

In her speech, she took on President Obama, Unions and Republicans who didn't push for more spending cuts. A lot of people are talking about her speech and the clash of Union and Tea Party protesters at the event. However, her speech has jump started another round of speculation of whether or not she will be running in 2012 when she concluded her speech with these lines:

"The 2012 election begins here. We will fight for America and it starts here in Madison, Wisconsin. Mr. President, game on!” 

Do you think this speech is her announcement that she's running in 2012?
