From FactCheck:

Of course, we can’t say what Palin considers “major.” But if Palin’s own ethics reforms in Alaska were important enough to highlight in her convention address, then it’s only fair to credit Obama’s efforts on that topic. In 1998 in the Illinois Senate, Obama cosponsored an ethics overhaul that bars elected officials from using their campaign funds for personal use and and was called the the first major overhaul of Illinois campaign and ethics laws in 25 years. It also bans fundraisers in the state Capitol during legislative sessions. Obama’s Republican cosponsor Kirk Dillard even appeared in an Obama ad last summer describing Obama’s skills working with members of both parties to get legislation passed.

In Washington, Obama was instrumental in helping to craft the 2007 ethics reform law that ended gifts and meals from lobbyists, cut off subsidized jet travel for members of Congress, required lobbyists to disclose contributions they “bundle” to candidates, and put the brakes on other, similar common practices.

In addition, we already noted in a recent article Obama’s efforts with Republican senators to help detect and secure weapons of mass destruction and to destroy conventional weapons stockpiles around the world, and to create a publicly searchable database on federal spending.
