Jeb Bush’s campaign is canceling its Iowa television advertising buy and shifting money to double staff on the ground in January, the final month before the high-stakes Iowa caucuses.

The news will raise questions about whether the former Florida governor might pull out of Iowa given his fifth-place status here, with just 6 percent support of likely GOP caucusgoers…

The larger context is that Team Bush is making similar shifts from TV ads to its ground game in other early states, too.

And Bush’s presence will still be prominent on voters’ TV screens: A pro-Bush super PAC has reserved more than $19 million in ads across the first three states in coming days.
