Two weeks ago, Sen. David Vitter began embarking on an ambitious project: He is reading the Gang of Eight’s 844-page amnesty bill. All the way through. And tweeting his concerns.

He hasn’t finished yet, but so far this has proven to be a very worthwhile exercise.

Unlike Sen. Marco Rubio’s chief of staff, Vitter leaves his Twitter feed unlocked so that anyone can review and critique his findings.

Too bad all members of Congress don’t read the bills they vote on.
