Think Santorum might be reaching with this one. From ABC News' Michael Falcone:

The Santorum campaign offered ABC News a sneak peek at their in-house delegate tally, which still shows the former Pennsylvania senator trailing Romney but in a much better position to catch him.

Here’s how the Santorum campaign sees the standings in the race for delegates:

Romney: 435

Santorum: 311

Gingrich: 158

Paul: 91

The Santorum campaign’s version of the count puts them 124 delegates shy of Romney. By comparison, the ABC News delegate estimate shows Santorum 268 delegates behind Romney.

Here is the ABC News delegate estimate:

Romney: 521

Santorum: 253

Gingrich: 136

Paul: 50

Uncommitted: 2

A candidate needs 1,144 delegates to clinch the Republican presidential nomination.
