• Wells Fargo recently admitted that 545 of its customers lost their homes after being improperly denied loan modifications that would have lowered their mortgage payments. With the Consumer Financial Protection Bureau rendered otiose by Republican control, expect Waters to step into the breach and start taking names.
• Deutsche Bank is deeply intertwined with both Donald Trump and Russian money laundering; it has much to fear from Waters. Go deeper.
• Also on Waters' list of priorities: housing, flood insurance and payday lenders.

What else is happening: The midterm elections changed the business landscape with both ballot measures and with new oversight in the House. Minimum-wage increases passed in Missouri and Arkansas, both of which were states where Republican lawmakers refused to make such a change on their own. Those statewide increases come on top of many city-level hikes.

Cannabis was also on many ballots:

• There was further legalization of marijuana in Michigan, Missouri and even Utah.
• Marijuana bulls were encouraged by the firing of attorney general Jeff Sessions, an adamant foe of the drug. It's unlikely that any of his successors will care as much about cannabis as he does.

Why it matters: Minimum wage hikes work, and voters know it. And while marijuana is going to remain illegal at the federal level for the foreseeable future, there is now a decent chance that Congress might pass a law ensuring that cannabis companies can be banked. That's a vital step for any industry.
