New Hampshire (4) _ Romney has a vacation home in New Hampshire, which is next to Massachusetts, where Romney was governor. He won the 2012 primary big, but Obama peeled off this Bush state in 2008 and has worked hard to keep it. Vice President Joe Biden visited Friday. But the GOP is back in power in the Legislature, and freshman Sen. Kelly Ayotte is seen as asset for Romney.

Ohio (18) _ This Midwestern state has been a general election bellwether since 1980. Romney won the 2012 primary and has support from establishment figures such as Sen. Rob Portman. Obama has the organizing advantage, although the economy remains a sticking point, especially in the industrial northwest.

Virginia (13) _ Long a GOP bastion, Obama carried Virginia in 2008 by turning out young and minority voters. An influx of under-35 crowd, especially from the Washington area, has continued. But Republicans roared back in 2010, ending consecutive Democratic administrations in governorship by electing up-and-comer Bob McDonnell.

LEANING REPUBLICAN (47):

Arizona (11) _ 2008 GOP nominee John McCain's single-digit victory in his home state, and Hispanic and young voter boom, give Obama hope that Arizona is trending as others in the Southwest. But Romney won big in February's primary, helped by the support of GOP Gov. Jan Brewer, in a state where Republicans and the tea party are in charge.

Indiana (11) _ Obama broke a 44-year GOP trend in 2008 by winning Indiana, albeit by a single percentage point. Unemployment is high and the tea party is a new factor, both working against Obama.

Missouri (10) _ Democrats have contested Missouri in the past three elections, only to lose each time. Democratic Sen. Claire McCaskill is in a tough re-election fight, and Obama's approval has dipped below 40 percent.

North Carolina (15) _ Democratic Gov. Bev Perdue's decision not to seek a second term this year, union anger about the Democratic National Convention in this weak union state, plus Obama's support for gay marriage, rejected in a May 8 referendum, are warnings that a repeat for Obama will be tougher.

SOLIDLY REPUBLICAN (159): Alabama, Alaska, Arkansas, Georgia, Idaho, Kansas, Kentucky, Louisiana, Mississippi, Montana, Nebraska, North Dakota, Oklahoma, South Carolina, South Dakota, Tennessee, Texas, Utah, West Virginia and Wyoming.
