Instead, it is the principal of running from a bear. You don't need to be faster than the bear as long as you are faster than your hiking partner.
These politician are becoming more "moderate" to stay out of the spotlight and the judgmental eye of the media. As long as they are not the most "extreme" they should stay safe and will not be singled out for defeat like certain congressmen in Florida.
If enough of these politicians were to man-up and turn around and confronted the bear like a certain ex-Speaker of the house now does, the bear would either run away and leave them alone or be defeated in the battle of ideas.
If you mean Gingrich, you're going to be deeply disappointed. Gingrich too is "running from the bear" as seen from his falling into the "inclusion" boilerplate b.s. too as seen here: http://thehill.com/video/campaign/266533-gingirch-says-hispanic-inclusion-necessary-for-gop. No one says Hispanics, blacks, women or anyone else can't be part of the GOP. I sure see a number of both in important governing posts and as speakers at the RNC. I don't see any sign on the door saying "Non-white males need not apply." This "inclusion" business is just code for becoming Democrats lite. I can see making the argument that conservatives need to do a better job at educational outreach to women and minorities to help them to understand how conservatism would best serve their needs and how liberalism has failed them. I would totally agree with that. But Gingrich by slobbering the media's inclusion line is just waving a white flag of surrender and conceeding a very dumb point the media is trying to make to weaken conservatism and the GOP. Why would anyone vote for the imitator when you could have the real thing?
