Democratic Senator Barack Obama won the Wyoming caucus Saturday with 61 percent of the vote to Sen. Hillary Clinton's 38 percent. A strong win in Wyoming was important to both campaigns after Clinton carried two delegate-heavy states March 4th: Texas and Ohio.

The heavily Republican Wyoming has just 12 delegates to help pick the Democratic nominee, one of the smallest totals in the race, but at this point every delegate has become crucial in the battle between the senators.

"This is a very important win for us," said David Plouffe, Obama's campaign manager, in a conference call with the Associated Press.

This is a very important win for us. David Plouffe, Sen. Obama's campaign manager.

Obama is projected to pick up at least seven of the delegates and Clinton at least four. Five more delegates will be awarded at the convention. Despite Clinton's recent win in two large states, Obama still has roughly a 100 delegate lead in the race.

While Obama had been predicted to win Wyoming as early as three weeks ago, Clinton put in a last minute push in the state in an effort to swing more delegates. Hillary, Bill and Chelsea have all cammpaigned around the state since March 4th.

With his 50-state strategy and strong ground campaign, Obama has traditionally done better in caucuses, which generally reward candidates based on campaign organization. In this primary season Obama has won 11 caucuses while Clinton has only won 2.

Now both candidates look ahead to the Mississippi primaries and more importantly the Pennsylvania primary on April 22.

Pennsylvania is expected to be closely contested and is the largest remaining primary.
