CUYAHOGA FALLS, Ohio — With polls showing him in a dead heat with Mitt Romney, former senator Rick Santorum (R-Pa.) brought his campaign here Monday night with the hope of getting an extra boost in Tuesday’s big Buckeye State primary.

But there’s just one problem for Santorum.

Even if his Monday-night rally helps to draw him support, he won’t be able to net any district-wide delegates here in Cuyahoga Falls.

Or, for that matter, in three of Ohio’s 16 congressional districts — starting him off at a major disadvantage against Romney in the delegate race.

That’s because last year, when Santorum was still just a blip in the polls, his camp failed to organize the necessary delegate slates throughout Ohio. (According to local party officials we’ve talked to on the ground in some parts of the state, even the delegates the Santorum camp does have in place were the result of an eleventh-hour scramble.)

Santorum’s camp has repeatedly brushed aside the fact that he is forfeiting delegates in nine districts here, not to mention the entire state of Virginia.

Does it matter in the end?

In a word, yes.

If it wasn’t clear before, Super Tuesday underscores the point that the race to the nomination is about one thing and one thing only: delegates. And today is just the latest step on the long road to Tampa.

Winning straw polls and beauty contests may be good for building momentum, but with former House speaker Newt Gingrich (R-Ga.) poised for a strong showing in the other big state tonight — Georgia — and with Romney favored in a handful of other contests, it’s hard to see where Santorum breaks through in the delegate race tonight.

So, it’s a bump in the road for Santorum. But if his closing argument against Romney in Ohio is any indication, the road is one he plans to travel for some weeks to come.
