TAMPA, Fla. (AP) - This is the convention prelude of the Republicans' dreams - their nightmares, that is.

Mitt Romney wanted to preside over a made-for-TV gathering showcasing his economic credentials and GOP unity. Instead, he's heading to Tampa with the national debate focused on rape and abortion and with the divisions within his party - and with running mate Paul Ryan - on full display.

Even the weather is threatening to spoil Romney's party.

All this as a new Associated Press-GfK poll shows a neck-and-neck race between Romney and President Barack Obama just over two months before the election. That's evidence that Romney didn't get a bounce of support by choosing Ryan as his vice presidential nominee.
