On the campaign trail, Senator Barack Obama has extended his delegate lead over Senator Hillary Clinton with a primary victory in Mississippi. Obama won with 61 percent of the vote. Both candidates were in Pennsylvania on Tuesday, host of a key primary in six weeks. Clinton spoke to supporters in the town of Harrisburg.

Sen. Hillary Clinton: “I want you to know that if you will work for me for the next six weeks, if we can put together a great victory across this commonwealth, I will be there day in and day out fighting for you in the White House, making a difference for you, your families, your jobs, your healthcare. Let’s go out and make history together.”

New results show Obama has also won the Texas Democratic caucuses. Because of allocation rules, CNN is projecting that Obama will net more delegates from Texas than Senator Clinton, who won the state’s primary. Also campaigning in Pennsylvania, Obama addressed supporters at a town-hall style meeting in Fairless Hill.

Sen. Barack Obama: “This is our moment. This is our moment to choose change over more of the same, to choose the future over the past. This is our moment to finally turn the page on the failed politics of yesterday. This is our moment to put the American dream within reach for every American.”
