Maybe a better way of restating what I said in previous posts is this:
No matter what people argue, whether our country is center-left or center-right, the key word is center. To appeal to those growing number of independents, a Party must move toward the center. For the Republicans, that means dumping the likes of Palin and Limbaugh. It also means that the moderates must denounce or at the very least, begin separating themselves from the far-right fringe. As an admitted Republican, I'd be quite surprised to see that happen any time soon, seeing as Palin has her following (sometimes I'd consider them, as Limbaugh has said, underestimated, but I also can see them as overestimated, misled, and embellished), and Limbaugh has many dedicated listeners. I, for one, don't back Limbaugh entirely (there are a few things that he will bring up that shed light on a few things within the Administration, but most of it is being pulled out of the place that sees no sunshine).
I think the next few months are going to be very telling. Both sides will over/down play it depending on who you ask, but I can see the strong moderate Republicans start to set themselves apart and appeal to a more broader base of Republicans and Independents. If the current situation continues (economy, jobs, health care), maybe the best thing for Republicans is to shut their mouths and let it all play out, and in response to the persistent problems, I see voters asking for a change or shift in policies, hence leaving the door open for Republicans in Congress.
These are my feelings and are open to interpretation and discussion, which I look forward to debating further.
