Personally, I'm not surprised. The tone of the rhetoric from the GOP has devolved from a debate about issues to people calling others names. The GOP seems to think it's ok to call those who disagree with them "socialists," "Commies," whatever. It was only a matter of time before the use of name calling became so common that it became part of the intra-party squabbling. I personally hope that the name calling will stop and both parties just focus on the issues.
