Last I checked Rand Paul supported Ted Cruz. He did say that the primary problem (with this issue) is too many Democrats rather than squishy RINOS which people, myself included, could argue about, regardless he has a point. Democrats stick together even when they know it's wrong. That is why they keep beating us. Then never compromise, never cave, never give in, and never become fractured. On the other side, the only time Republicans take the gloves off and fight like they really mean it is when they are fighting other Republicans. I'm not sure I approve of Rand's seeming effort to calm the waters in this particular case, but the Republican party needs to get it's act together. That could start by not saying that someone that supprts Cruz is undercutting him.
It would also be nice if the RNC grew a pair and started sanctioning "republicans" that vote as democrats.
