Michelle Bachmann, who is known for wanting to possibly investigate Democratic members of Congress for ill-defined "unAmerican activities," as well as wanting to create a "Tea Party caucus" within the GOP (and wanting to head that caucus), may end up running to be the Republican Conference Chair, after current Chairman Mike Pence said he would step down.
It's not confirmed, but if it did happen, I'll tell you something right now - it's not going to be pretty. Bachmann is a fairly ruthless, uncompromising personality that is more likely to use the position as a simple launchpad for her career to somewhere else, rather than work to ensure the day-to-day operations of the Republican Congress are stable and maintained. Pence, who though similar to Bachmann in a lot of ways, helped keep the pack of the GOP together and unified under some trying times. Bachmann is more likely to go on a witch hunt of remaining GOP moderates than do anything to ensure the stability of the GOP. I'm not saying she is likely to cause big fractures and tumble Congressional favourability down to nearly 0, but, simply, it ain't going to be pretty.
Whether or not Bachmann actually goes for it, remains to be seen. However, she's going to be a pain in the side of presumed-Speaker-elect John Boehner, as quite a few of these new "Tea Party" candidates will. More on that later.
