Here's another addition to what's turning out to be an active few weeks in the quiet GOP presidential primary campaign for 2012. Minnesota Gov. Tim Pawlenty (R) has announced plans for a "Facebook Town Hall" this Wednesday. His camp says it's the first such event for a major political leader.

"Governor Pawlenty will make a major announcement over Facebook and will seek input from Facebook uses on helping Republicans win the 2010 elections and stop runaway Washington spending," the page announces.

An aide says Pawlenty will appear via video on the social networking site and answer user-submitted questions in real time. He'll also make what the aide bills as "a major announcement about the PAC's political activities." Expect to hear an announcement about candidates Pawlenty's Freedom First PAC is backing.

Wednesday is the final day of the first quarter FEC filing period, so the event could also serve as a final public pitch for more donations for his committee. It's scheduled to begin at 7:15 pm Eastern.
