Matthew Yglesias has a great look at the size of bills on Capitol HIll and disingenuousness of Republicans who complain about a bill’s length.
The bill is long in part because it’s a complicated bill with lots of words in it. But part of the issue is that bills are printed up with large type and a lot of spacing. I’m not exactly sure why they’re formatted this way, but anyone who’s ever worked on the Hill—including Republican members of congress of course—knows this perfectly well.
