Florida Rep. Connie Mack is expected to announce he's running for U.S. Senate Friday.
A release is billing the 10 a.m. rollout at the county courthouse in Ft. Myers as a "major announcement regarding the 2012 race . . . against liberal incumbent Bill Nelson."
Mack will be the third official Republican to enter the campaign, following former Col. Mike McCalister and Senate President Mike Haridopolos.
I'm personally a bit surprised to see Mack get in this early, but maybe he thinks he can kinda-sorta clear the field this way (and dry up the stumbling Haridopolos's fundraising, if it hasn't already done so on its own). But despite his natural advantages, he's not a perfect conservative, and the teabaggers always sniff blood.
UPDATE: WHOA! Stop the presses! Literally! Josh Kraushaar is tweeting that Mack will NOT be running, and, believe it or not, that his big announcement tomorrow will consist of an endorsement of Haridopolos:
Top FL GOP source says Mack NOT running for Senate, likely running for re-election instead...
Buzz is that he will be endorsing Haridopolos at announcement tomorrow
