I think he's much tougher on Wall Street if you look at and include his stance on taking big money out of politics.

HRC might say she wants to reform Wall Street but I think it's gonna be hard for her to seriously commit to making campaign finance reform. She can say things about campaign finance reform all she wants, but given the recent actions by the DNC removing the ban on lobbyist contributions, it's hard for me to believe that she's completely telling the truth. If you look at her website regarding the issue:

Overturn Citizens United. Hillary will appoint Supreme Court justices who value the right to vote over the right of billionaires to buy elections. She’ll push for a constitutional amendment to overturn Citizens United in order to restore the role of everyday voters in elections.

She mentions this every now and then (usually in the debates), but Bernie is constantly pushing this message.

End secret, unaccountable money in politics. Hillary will push for legislation to require outside groups to publicly disclose significant political spending. And until Congress acts, she'll sign an executive order requiring federal government contractors to do the same. Hillary will also promote an SEC rule requiring publicly traded companies to disclose political spending to shareholders.

She doesn't seem to mention this very often during her speeches. Again Bernie is constantly mentioning campaign finance reform.

Amplify the voices of everyday Americans. Hillary will establish a small-donor matching system for presidential and congressional elections to incentivize small donors to participate in elections, and encourage candidates to spend more time engaging a representative cross-section of voters.

Why hasn't she done so already? When she asks for contributions in various emails, it's usually for $1 to $5. ^{1 2}
