SOUTHERN ARIZONA (SGT NEWS) - Both Republicans and Democrats are preparing for the most significant day in any presidential campaign season where voters in more than 20 states head to the polls, Super Tuesday. Candidates plan on jet-setting across the nation to deliver speeches, run campaign ads and give voters one last opportunity to hear them speak before the February 5th vote.

Senator Barack Obama plans to spend tens of millions of dollars on campaign ads across 24 states, fueled by his $32 million fundraising achievement in January. Clinton only plans to fill television screens with her ads in half of those states. Governor Romney will spend several million (including $1 million in California alone) while John McCain and Mike Huckabee are expected to spend significantly less.

McCain's senior adviser said his campaign is treating February 5th as a "de facto national primary" as the Arizona senator races through 17 states in a crash-course for delegates. "We expect to come out of the fifth with a very large delegate count."

Texas Representative Ron Paul is focusing on recruiting precinct leaders throughout the remaining states and is planning targeted advertisements in specific states before Super Tuesday. Paul made recent campaign stops in Colorado and Washington and is expected to stop in North Dakota early next week.

More than 1600 delegates are at stake for the Democrats and 1000 for the Republicans on Tuesday.

Some analysts predict February 5th may not provide a good enough indication on who the winner will be, however. "I do think that you are not going to come out of February 5 with somebody with an enormous lead in delegates," said John Fortier, who monitors U.S. politics at the American Enterprise Institute in Washington. "Even a pretty solid win by one of the candidates would probably be 55 percent of the delegates to 45 percent. That still leaves open the possibility that later states could change the outcome," he added.

An ABC News/Washington Post poll recently published puts Super Tuesday's popularity falling just short of the Super Bowl's by three percentage points, 40 to 37. Among those who describe themselves as sports fans, 63% favor the Super Bowl over Super Tuesday, while the February 5th primaries outrank the championship game by a 48-17 percent margin among those who are not fans of the sport. The poll also indicated that 53% of “educated” voters favor Super Tuesday.
