The rollout of legislation this week that would rip up much ofthe Dodd-Frank Act marks a pivotal moment for Republicans' effortsto overhaul post-crisis financial rules.

It's also an opportunity for Democrats to push an agenda thatGOP lawmakers and finance executives are less keen to talk about:breaking up Wall Street megabanks.

The Republican bill, drafted by House Financial ServicesCommittee Chairman Jeb Hensarling, has a lot that banks like. Itwould repeal the Volcker Rule, which restricts lenders from makingspeculative bets unless they use clients' money. And it wouldreduce the frequency of burdensome exams that determine whetherbanks can pay shareholder dividends. House Speaker Paul Ryan ofWisconsin told reporters on Wednesday that he'll seek a vote on themeasure “as quickly as possible” after it's approved byHensarling's committee.
