Middle-of-the-roaders and people who don't pay a lot of attention to politics have made such a fetish out of bipartisanship that the most partisan political hacks in D.C. will go on and on about "unity" and "working with the other side" even as they lustily plant toe kicks to the other side's groins at every opportunity. To the moderates, this makes little sense. Why can't both sides get together, buy the world a Coke, teach them to sing in perfect harmony, and keep it company....la, la, la, la!Gosh that does seem silly. Moderats should probably argue instead that both sides find common ground where they can, and work to improve things rather than constantly bickering.
Moderates might also point out that both parties are more interested in defeating their political enemies rather than passing legislation that would improve things.
Of course that is what Moderates actually do, but Hawkins finds it easier to make up some beliefs for Moderates and then mock them. He then points out that we are better off not passing any legislation anyway, which is certainly a conservative position.
