CASTLE ROCK, Colo. - Could it be a preview of 2016?

Former Florida governor Jeb Bush took a swipe at Hillary Clinton Wednesday night at a rally for Republican candidates here in Colorado.

"This last week I saw something that was breathtaking. A candidate – a former secretary of state who was campaigning in Massachusetts, where she said don’t let them tell you that businesses create jobs," Bush said as the crowd booed. "The problem with America today is not enough jobs are being created, but they are created by businesses."

Of course, the former secretary of state was Hillary Clinton. She later backpedaled on the remarks, saying that she "shorthanded this point," and the economy grows when good-paying jobs are created.

But it was enough for Republicans to pounce, and Bush, who is said to be mulling a run for the presidency, used it to jab at Clinton, who is, as we all know, thinking about it too.

Bush appeared at a rally with Republican candidates at the Douglas County fairgrounds, where attendees sat on bales of hay. Bush spoke between a slate of statewide and Congressional candidates and Bob Beauprez, who is running for governor, and Senate candidate Cory Gardner.

"Imagine a Republican controlled Senate and House of Representatives," Bush said, and start "beginning to paint what that agenda looks like."

Bush is seen as pivotal to helping reach the key, growing Hispanic vote for Republicans. Bush, who speaks fluent Spanish, recorded Spanish-language ads for candidates in three states, including Gardner. Bush appeared at a rally with Gardner and Beauprez earlier Wednesday where he answered questions in Spanish.
