Bush spends millions on TV but has yet to rise in GOP race

DUBUQUE, Iowa (AP) — Jeb Bush and his allies are spending circles around his rivals for the Republican presidential nomination. Yet for all the money they've invested — $26 million on television ads alone — they've yet to see a substantial return.
Having fallen from summer front-runner to autumn afterthought, the former Florida governor made deep spending cuts to his campaign operation in October. But he and his backers plowed ahead with a television blitz three times the size of anyone else's, while putting a new strategic focus on New Hampshire.
