Republican presidential race: Why so many long shots are running

When John Kasichannounced his candidacy for the Republican presidential nominationthis week, the respected Ohio governor was entering an already crowded field with15 other candidates, most of whom have little or no chance of winning.

Kasich joined, among others, Carly Fiorina, Mike Huckabee, Rick Santorum, Ben Carson, Lindsey Graham and George Patakiall of whom, despite facing embarrassingly low pollingnumbers anddaunting odds, havedecided to forge ahead with their campaigns.

So why do long-shotpresidential candidatesgo to all the trouble not to mention time, energy and millions of dollarson a venture unlikely to produce a successful result?

"I do think that in order to get into politics you have to be able to get up in the morning and look in the mirror and say 'Good morning, Mr. President,'" saysDaniel P. Franklin, a political scientist at Georgia State University and the author ofPitiful Giants: Presidents in their Final Terms.

"Politics is a business in a sort of a metaphorical sense," he says, "and the top of the business is the presidency. So anybody who'sworth their salt gets into that business with the idea that one day they'd like to be at the top."

That notionalso takes into consideration, as Franklin outlined in a recent article in Newsweek, that anyone has a chance.

In that piece, he cited the famous example Jimmy Carter, the one-term governor of Georgia who came out of nowhere in 1976 to claim the Democratic Party nomination and win the presidency.

And then of course there's the case of the former first-term senator from Illinois, a guy named Barack Obama.

'Well,why not me?'

"I think when Obama started off he was pretty much a longshot," Franklin said in an interview."He was a senator who hadn't finished a single Senate term. And he had no military experience and no executive experience, and he goes on to win."

"So that's whatPataki or Ben Carson orCarly Fiorina, or some of those other people are looking at. They're looking at it and saying 'Well,why not me?'"

At the same time,as consumer advocate and former presidential Green Party candidate Ralph Nader suggested somewhat cynically in a recent column in the Los Angeles Times, "short of winning the presidency, however, there are many other rewards for running."

"You can fatten your mailing list and your Rolodex for future opportunities," Naderwrote. "These can include lucrative jobs, retainers, paid speeches or book advances."

Also,by staying in the limelight, as former Arkansas governorMike Huckabeedid after his failed attempt at the Republican nomination in 2008 he signed on to host a talk show onFox News once and future candidates canset themselves up for a second run.

For someone like Huckabeethis would almost certainly be alast shot. But for younger candidates, theso-calledlong game is certainly another reason for enteringthe field.

While the odds of winning are slim,theybenefit from getting their name out thereand possibly securing a convention speech and creating buzz for the next cycle (as Obama did).

People like Huckabee, though,or Rand Paulor Rick Santorum for that matter, also run to represent an ideological wing of the party forHuckabee and Santorum, it isthe social conservatives, for Paul, the libertarians.

"Ideological candidates represent the purists in the party," Franklin wrote in Newsweek. "And because purist money doesn't dry up just because their candidate is losing, true believers can stay in the race for longer."

Single-issue candidates

Similar to the purists are the single-issue candidates. Billionaire businessmanRoss Perot, for example, ran as an independent in 1992 and as head of the Reform Party in 1996mostly to bring attention to budget deficits. And publishing scion Steve Forbes was all about campaigning for a flat tax when he sought the Republican nominations in 1996 and 2000.

In a more realistic way, some long shotsmay simply be hoping that a decentrun could net them agig as vice-president or some kind of a cabinet position, saysRepublican strategist Ford O'Connell.

Candidates like Pataki, Graham (a long-serving congressman, now senator)or Kasich perhapsparticularly Kasichwho comes fromthe battleground state of Ohio all have the resumsto be considered running mates.

"I think Graham is one of those guys who's reached a point in his life where you give it a try, and when you don't embarrass yourself you can parlay that into other things," O'Connell said.

O'Connellwhittled it down to three reasons as to why anyone runs, including those with a good chance of winningand those who almost certainly will lose.

"The first is they're looking for a media deal radio, bump up theirname identification. Second is that they'repotentially looking to run for a cabinet position ofanother office down the line.

"And the final one is they're actually in it to win it."
