If you’re still concerned about Mitt Romney’s adherence to conservative principles, Tim Carney‘s latest report for the Washington Examiner will offer you little solace. Carney probes high-dollar contributions to the “super-PAC” supporting Romney.

Increasing taxes, capping greenhouse gasses, legalizing gay marriage, and backing Hillary Clinton for president — these are the recent political and policy priorities of Mitt Romney’s very biggest financial backers.

While Romney’s Florida victory spurs talk of inevitability, exit polls show him still struggling among conservatives and Tea Partiers. Campaign finance reports filed this week reveal a gulf between the GOP base and Romney’s funding base.

Financiers Julian Robertson, Paul Singer, and Miguel Fernandez all gave $1 million to Romney’s shadow campaign — Restore Our Future, the super-PAC supporting Mitt Romney and run by former Romney aides. …

… Robertson’s million-dollar donation to Romney doesn’t mean Mitt is a cap-and-trader or a tax-increaser. Singer’s million-dollar check doesn’t suggest Mitt is pro-gay-marriage. And Fernandez’s million doesn’t make Mitt a Charlie Crist.

But it’s revealing that these are Romney’s biggest donors. At the very least, it highlights the difference between the GOP’s electoral base and its money base.
