How come Mccain can make such huge mistakes, mixing up shiia, sunni, comparing Purim to Halloween..is that ok?

Well, I chalk it up to confusion or fatigue. All of the candidates have to keep a lot of info straight in their heads. Sometimes people just slip up, it's happened to Clinton and Obama too. I just try to recognize that all three of them are very stressed and working 20-hour days towards the White House. We shouldn't be so hard on them all the time, they're human just like you and me. Don't throw stones from gl houses. If you've never made a mistake, don't criticize others for getting confused.
