Regular migraines are either caused by some serious medical disorder or by stress. If it is not a medical disorder, this woman has something going on in her life she cannot deal with, emotionally. I've never met anyone who has migraines this seriously who did not.
Anyone who suffers from migraines the way Michele Bachmann does has my full sympathy. It makes my head hurt, just thinking about it. I have made no secret that I think she is the GOP version of Barack Obama, unqualified and getting a free pass from the right, the way Obama did the left. This said, having a problem with migraines is not a disqualifier. What it does say is this is a woman has something going on in her life that is putting such stress on her that she cannot cope any other way.
If this is how she handles stress, it is possible she may not be capable of handling the stress of the job. You can't keep (allegedly) going to the hospital and basically being knocked out on a weekly basis. It just doesn't look good. It makes women in politics look bad - and that has been my big complaint about her all along.
Now I do have a headache, just thinking about her! I'd better deal with it. I keep telling myself she cannot win the nomination, she cannot win the nomination. There.... I feel much better!
