Barking up the wrong tree blog concludes:
"Congressmen who are less covered by the local press work less for their constituencies: they are less likely to stand witness before congressional hearings, to serve on constituency-oriented committees (perhaps), and to vote against the party line. Finally, this congressional behavior affects policy. Federal spending is lower in areas where there is less press coverage of the local members of congress."
This is particularly interesting and perhaps troubling as newspapers (especially local newspapers) find themselves unable to stay afloat financially, and are thus cutting back on constituency-oriented political coverage.
