Presidential Wannabe seeks to negotiate with our enemies but can't even negotiate a public financing agreement with McCain

So the presidential candidate that seeks to negotiate with our enemies can't even hammer out a simple agreement for public financing with his political opponent:

In February 2007, I proposed a novel way to preserve the strength of the public financing system in the 2008 election. My plan requires both major party candidates to agree on a fundraising truce, return excess money from donors, and stay within the public financing system for the general election. My proposal followed announcements by some presidential candidates that they would forgo public financing so they could raise unlimited funds in the general election. The Federal Election Commission ruled the proposal legal, and Senator John McCain (R-AZ) has already pledged to accept this fundraising pledge. If I am the Democratic nominee, I will aggressively pursue an agreement with the Republican nominee to preserve a publicly financed general election.
