Oct. 29 (Bloomberg) -- Barack Obama leads in Florida and Ohio, states Republican John McCain must win to capture the presidency, as voters prefer the Democratic presidential nominee's personal traits and approach on the economy and health care.

Obama, an Illinois senator, tops Arizona Senator McCain by 50 percent to 43 percent among likely voters in Florida, a Bloomberg/Los Angeles Times poll shows. He leads 49 percent to 40 percent in Ohio, as voters in the two states overwhelmingly rate domestic concerns as more important than national security.

Voters choose Obama, 47, as the candidate best able to handle the financial crisis and health care. And by an almost 2- to-1 margin, they say the Democrat has ``the better temperament and personality to be president.''

``Domestic issues are the outstanding issues of the day, and Obama has been owning those,'' says Susan Pinkus, the Los Angeles Times polling director. What is more, ``voters are more comfortable with him'' after his three debate performances.

Florida voters by more than 2-to-1 say a candidate's views on domestic issues such as health care and the economy are more important than positions on the war in Iraq and terrorism; voters in Ohio say the same by a 3-to-1 margin. (Bloomberg)
