Lets take the two ways the rules changes could be implemented issues side by side.
1. Let us concede, if it indeed becomes the way the new rules work, that Whoozeyerdaddy would be right in saying "Proposed bill goes to committee. The guy who wrote it tells the chairman what's in it. (Plus he's owed a favor) Nobody reads it. Hell, nobody else was in the committee for that matter. He holds proxy for all his party-mates. The chairman rubber-stamps it through committee where it goes to the floor."
This is indeed the way the GOP often proceeded in the house when they held the majority during the 2000-20006 time period. It was wrong then, and would be wrong on the part of the dems now.
2. If on the other hand, a bill is presented openly, everyone has a chance to read it and comment on it in committee and in public, and then debate and especially amendments are limited, the bill is not endlessly delayed, corrupt dealings on earmarks are reduced, and bills can't be delayed endlessly.
Which was what the last GOP congressional minority did, and it was likewise wrong.
We will see which of the two become the case with the new house rules, and we can't prejudge now until we see the results.
