Former Massachusetts Gov. Mitt Romney could clinch the Republican presidential nomination after Tuesday's primary in Texas.

Romney needs just 60 delegates to become the official party nominee.  More than 150 are at stake in the state's primary.
    
Since Romney is the only candidate still campaigning, he's likely to gain a majority of those delegates.

"That goal is accomplished, but there's a much bigger goal to be accomplished and that's winning the presidency," Rich Beeson, Romney's political director, cautioned.

"While you can take a certain amount of satisfaction and pride for (Romney) and what he's accomplished, he's very resolved to say, 'Our work isn't done,'" he said.
