Threatening to sue in a Primary Election does not seem like sticking up for oneself Instead it fits a pattern that an awful lot of people seems “out there”
Try to understand how insulting it is to many Christians to have a candidate claim to be a great Christian, to have his father claim he is anointed by God, and see him preaching in a church, and then he turns around and says lies, such as that Trump bulldozed a woman's house (he did not), that he will destroy the 2nd Amendment (that's preposterous), or to have made robocalls claiming that Carson and/or Trump are quitting the race, and so forth. It's deeply offensive to have Christianity represented this way.
