Something else to consider: There is increased pressure from the large growth in the number of off-road vehicles. As a single example, look at the sales growth for Polaris (in a poor economy, no less):

Off-road vehicles dominate their product line and profits. I can understand, and maybe even support disabled folks using these machines, but we all know the majority of new buyers are able-bodied. Why don't they want to get out and hike or trail run?
The ads and commercials for these machines tell the real story - adrenaline, power, noise... Not an attitude I personally appreciate in the backcountry. I know there are exceptions to this - some of 'em frequent WtW and are responsible good people. But, I am afraid they may be in the minority, based on the number of rude, clueless, noisy, exhaust-fuming jerks I've encountered on the local FS roads and trails. Sorry to say it. I put a lot of blame on marketing and even X-games.
Finally, if more areas are designated for off-road vehicle use and the sales numbers continue to grow, what areas will be sacrificed in the next bill? Where will this stop?
So much for being a peacemaker, I guess.
