Mike Murphy: "There's lots of spin out there concerning fund-raising numbers for GOP presidential candidates. Federal Election Commission filings are quarterly X-rays of campaign bank accounts, which political junkies pore over like treasure maps. And as the July 15 filing deadline looms, campaigns are leaking bits of information, trying to show early strength. You may hear a lot of bragging about organization and ads, but don't be fooled: It's often a campaign's accountant who is the craftiest operator on the team."
