I think both candidates should vow to reinstate the Glass-Steagall Act if elected, or explain why they wouldn't in the televised debates.
Why is this important?
A petition to the moderator of the presidential debate to ask each candidate to take a stand on the reinstatement of the Glass-Steagall Act, aka, the Banking Act of 1933 that limited commercial bank securities activities and affiliations between commercial banks and securities firms.
