I couldn't disagree with you more on this point! We WIN only when we draw a clear distinction between us and them!
Who's the "us" and the "them" here? The only distinction drawing I see is intra-GOP, with each faction desperately trying to distance itself from the other. I see very little coherent distinction-drawing between the GOP as a whole and the democrat party, except for the occasional negative barb that's tossed out.
On top of which, drawing distinctions is not sufficient to win. The democrats are quite good at drawing distinctions between them and the GOP, but they then take the next step and say why that distinction matters, which includes a healthy dose of "because the republicans want to take __________ away from you." The GOP doesn't seem to be able to get out of first gear on this one, other than to say "we have to cut this and that and, ... oh, wait, not that, and that over there ..." without ever giving a good, down-to-earth explanation for why, in a way that would convince, e.g., a union member who's becoming dissatisfied with what he sees union management doing. Not only does that sort of distinction-drawing not work, it in fact aids and abets the democrats because it feeds right into their narrative about how republicans want to take away everything the poor and middle class have ever gotten.
Real conservatives do exactly that all the time but because of the complicit media it NEVER gets any coverage much less an honest debate!
They have yet to do it here and, with all due respect, Myst and R4P&C are not exactly "complicit media."
