Blink and you'll miss 'em. With only 48 hours to go before 2008's SuperMegaDuper UltraMonsterTsunami national primary, the five leading presidential hopefuls are focusing on air time, not face time--both on the airwaves and in airplanes as they fly between (and advertise in) the more than 20 states set to vote on Tuesday. Because you can't be everywhere at once--and, sadly, neither can Stumper--I've compiled handy guides to each candidate's sprint to the finish: the Pitch, the Stops (since Feb. 1) and the Ads.

Taken in total, the commercials and itineraries reveal how the campaigns are tackling the challenge of getting their messages out to nearly half the country for a single day of voting.

On your marks. Get set. Go:

HILLARY CLINTON:

The Pitch: It's the economy, stupid--and only I can handle it. Oh, and Republicans are going to eat that Barack Obama character alive. "Frankly, you know, in his prior election in Illinois, Senator Obama didn't face anyone who ran attack ads against him," Clinton said this morning. "He ran against a very weak opponent, without resources or credibility. I've been taking the incoming fire from Republicans for about 16 years now, and I'm still here, because I have been vetted, I have been tested." She's also criticizing his health care plan.

The Stops: Everywhere and anywhere--especially Latino areas. Since Friday, Clinton has visited San Diego, San Jose, San Francisco and Los Angeles in California; Tucson, Ariz.; Las Cruces, N.M.; St. Louis and Bridgeton in Missouri; and Minneapolis, Minn. Tomorrow, she'll hit New Haven, Conn.,Worcester, Mass. and New York City. She also stumped in New York, New Jersey, Connecticut, Massachusetts, Arkansas, Georgia and Tennessee while Obama was campaigning South Carolina. Meanwhile, Bill Clinton has handled African-American and rural areas, swinging through Pine Bluff and Texarkana in Arkansas; Kennesaw, Georgia; Huntsville, Alabama; Columbia and Springfield in Missouri; and four black churches in Los Angeles. Whew.
 
The Ads: 

Arkansas: Remember me? Your former First Lady?

Bobby: A Kennedy likes me, too.


Freefall: Be afraid. Be very afraid. (Read more here.)

Can Do: Obama's "political promises" won't fix the economy. My flags, sunsets, babies, and multicultural supporters will.

Lifetime: I can speak in normal human tones.
 

BARACK OBAMA:

The Pitch: Hillary's the boring old past; I'm the sparkly future. Plus she's too much like John McCain--and too polarizing--to beat him next November. "Barack Obama is the one candidate who offers a real choice and a real contrast against John McCain," spokesman Bill Burton said today. "He opposed the war before it started, never supported a bankruptcy bill that would make it harder for families to climb out of debt, and hasn't supported NAFTA or permanent trade with China that have sent millions of jobs overseas." So wait: you're saying that Ron Paul won't win the Republican nod?

The Stops: Coast to coast, with a focus on Latino hot spots, key caucus states and big media markets. Since Friday, Obama has ba-racked Albuquerque and Santa Fe, N.M.; Boise, Idaho; Minneapolis, Minn.; St. Louis, Mo. and Wilmington, Delaware. Tomorrow he stops in East Rutherford, N.J., Hartford, Conn. and Boston, Mass. before heading back to Chicago.

The Ads: 

Super Bowl: I am young and energetic, much like rock 'n' roll music. (Airing during the game in Alabama, Arizona, Arkansas, California, Connecticut, Delaware, District of Columbia, Georgia, Kansas, Louisiana, Maine, Maryland, Massachusetts, Minnesota, Missouri, Nebraska, New Jersey, New Mexico, New York, North Dakota, Oklahoma, Utah, Virginia and Washington.)

Inspiring: I've actually accomplished some stuff. Yes really. (Read more here.)

Caroline: Jack is Back!
 

 
JOHN MCCAIN 

The Pitch: I'm going to win--and I promise to make this as painless as possible for all you haters on my right. "I assume that I will get the nomination of the party," McCain said Tuesday. "I assume unifying our party is a very critical item and I believe we can do that and get everybody together and working together." Memo to McCain: telling the Washington Post that "it's not social issues I care about" won't help.

The Stops: A little bit of everything, with stops in northern strongholds and weaker regions--like, say, the South--where McCain could stand to gain a few delegates. So far this month, Mac has stumped in Chesterfield, Mo.; Chicago, Ill.; Nashville, Tenn.; Atlanta, Ga.; Birmingham, Ala. and Fairfield, Conn. Tomorrow he lands in Boston, Mass. and Hamilton, N.J.

The Ad:

True Conservative: Listen up, Rush: I am a "proud social conservative." Now let me talk about Iraq.
 

 
MITT ROMNEY

The Pitch: McCain is an older, male-r version of Hillary Clinton. Huckabee is a goner. I'm the last conservative standing. Also, Washington is Broken ®. "This is a battle in some respects for the heart and soul of the Republican Party," Romney said today. "Frankly, if we want a party that is indistinguishable from Hillary Clinton on an issue like illegal immigration, that we're going to have John McCain as a nominee, that's the wrong way to go."

The Stops: States that allocate delegates via caucuses and conventions, where organization can trump name identification, momentum and inevitability--and ideological activists typically turn out. Also important: Republican-only primaries. Since Thursday, Romney has stopped in Southern California, Colorado, Minnesota, Missouri and Illinois, while his wife and sons have fanned out over Georgia, Montana, Maine and North Dakota.

The Ads: 

Experience Matters: We can only afford one national ad before Super Tuesday to brake McCain's momentum. How about this three-month old anti-Hillary spot?
 

California: Help me, economic conservatives of Southern California. You're my only hope.

 
MIKE HUCKABEE

The Pitch: Sure, Sen. McCain, I'll keep the South and the evangelicals just out of Romney's reach on Super Tuesday. No need to thank me--yet. "I think it is time for Mitt Romney to step aside," Huckabee said this morning on CNN. "The fact is, he spent $100 million to have the same market share that I have for $7 million.  Now anybody with a Harvard MBA ought to know that the business model on that is, it is time to pull the plug on a business that is just not selling that well. And the real challenge is to -- if he wants to call it a two-man race, fine, but that makes it John McCain and me."

The Stops: Dixie. After leaving Southern California on Thursday, Huck has barnstormed in Alabama and Arkansas.

The Ads: None. We hear they're pretty pricey these days.
