It’s not really that hard to understand. The 20-25% that support Romney are RINOs, and they will never support anyone else besides maybe Huntsman. Bachmann’s interests are best served by attacking those that could bleed support to her.
True, and that makes sense from a business-like standpoint of politics. But I had always thought of her as more of an idealist. She’s coming across as a leech, which is very much beneath her.
I wouldn’t mind her as president (she was my first pick early on in the race), but she’s got a LONG way to go.
