Obama battles Romney tax proposals in key swing state

US President Barack Obama argued in the battleground state of Ohio that the tax proposals of his Republican challenger Mitt Romney would be good for China and other countries, but bad for the US.

Mr Obama has campaigned repeatedly in Ohio, a critical industrial state that does not reliably vote Republican or Democratic. The few so-called swing states like Ohio are expected to decide the presidential contest in November’s vote.

There has seldom been a US presidential election that looked to be as close as the two battle against a backdrop of economic uncertainty and 8.2% unemployment.
