Hillary Clinton needs a GPS unit and a calculator.

In early January, after a narrow win in New Hampshire, Democratic presidential candidate Sen. Hillary Rodham Clinton told a gathering of voters that she had “found her voice.” Along the campaign trail we’ve also repeatedly heard about her “roadmap.” And most recently, shortly after winning the Texas, Ohio, and Rhode Island primaries early Wednesday, Clinton told onlookers that her campaign has now “turned the corner,” and “we’re going on, we’re going strong, and we’re going all the way.”

Let’s hope that before she does–if she does–someone in her posse stops by the nearest Radio Shack and purchases HRC a portable GPS system. She’s going to need it. Before the now infamous Clinton “Red Phone” TV ad that ran this past weekend, her campaign bus was racing off the paved road and headed for the proverbial cliff.

She’s also going to need major help finding her way to the finish line ahead of Barack Obama. That path appears to be rocky at best for Clinton. No matter how much positive spin Clinton pedals between now and then.

She also obviously doesn’t have a calculator in her purse or she would be able to do the math and see that winning the Democrat race outright simply doesn’t add up based on the current delegate numbers.

But it’s not the delegate numbers that Clinton is concentrating on right now, it’s the numbers in her campaign’s bank account. As long as those numbers continue to increase, HRC is determined to stay in the race. In her mind, she’s come too far, and survived too many potholes, to park her political aspirations just yet.

Something tells me that we the voters would all be wise to “buckle up” in the coming weeks. The race is about to become even more unpredictable and incalcuable.
