I do not think it is a good idea to celebrate MLK's birthday with a money bomb. That might be fine if it was AFTER the Republican primaries, but it is not. MLK is not exactly loved by rank and file Republicans, because it was widely believed that he was a communist sympathizer.
Um, I'm pretty sure MLK's approval ratings in this country are like 98%.... I can't imagine anyone would ever complain about a campaign celebrating the civil rights movement's greatest leader. There are very good reasons to not worry about a 1/15 moneybomb right now - but this isn't one of them.
