‘Netroots Hitting LCD Ceiling?

Hugh Hewitt makes the case that they are:

If the netroots is all it’s cracked up to be, shouldn’t Edwards be far ahead in the online metrics and be more competitive in the polls? Instead, Obama is ahead on those metrics, and he’s the one who HASN’T engaged the movement.
The netroots footprint on this primary is limited in scope and well defined. Lo and behold, they aren’t the largest constituency in the Democratic Party. They aren’t even the largest constituency online.
See, Barack Obama has mobilized people, even if he hasn’t mobilized the netroots. He’s brought in students, African Americans, and apparently, young females. These are groups that are relatively apolitical. That’s why when you loosen the likely voter screen just a little, Obama does a lot better.

But for all that they celebrate bringing new people into the process, the fact remains that Obama’s voters are not the netroots. Demographically, the netroots are older (45 is the median), whiter, and more academic. They are fairly conventional liberals and “supervoters” — turning up in every general and most primaries. Obama’s voters are not. Not only is Obama not talking to the netroots; like Hillary, he has made a calculation that he does not need the netroots.
The core reason for Jerome’s alienation is that the netroots are losing a battle for relevance to a bunch of Obama-supporting, Facebook-addled college kids. When the second quarter closes, it will probably be announced that Obama has raised at least $15 million online, three times what Dean did at this point last cycle, and about twice Edwards’ total. Obama has done it with some netroots support, but the not inconsiderable difference between him and Edwards is due to a cult of personality that matters far more than anyone’s support on the blogs.

Is it time for the rightroots to rise, or is this a lesson in not over reaching?
