Back in January, Herman Cain announced an exploratory committee for president. A release from Herman Cain’s press office informs me today:

Longtime corporate executive and conservative leader Herman Cain will announce his decision regarding a potential presidential campaign on Saturday, May 21, 2011 in his hometown of Atlanta, Georgia.

The release goes on to state:

Cain is widely believed to have been the winner of the first 2012 Republican candidate debate Thursday evening in Greenville, SC, and has steadily gained grassroots and financial support across the U.S.

Now, call me crazy, but if your exploratory committee is touting a debate win and growth in grassroots and financial support, somehow I get the idea that a formal campaign announcement is in the works.
