"Exurbs" emerge as battleground in U.S. race

HENDERSON, Nev./WASHINGTON (Reuters) - First came the foreclosure crisis. Next, gas prices went through the roof. Now, beleaguered Americans living on the edge of metropolitan areas face a third plague: politicians.

Political campaigns call Carrie Mercherle's sewing machine shop in the Las Vegas suburb of Henderson four or five times a day, seeking her vote in the presidential election on November 4.

Mercherle generally hangs up before they can start their pitch.

"We're just very tired of it," Mercherle said. "It's like, just get (the election) over with already."

Fast-growing "exurbs" like Henderson, commuter towns outside the traditional suburban belts surrounding cities, have emerged as a crucial battleground in the 2008 election as Democrats consolidate their hold on older, inner-ring suburbs, many of which once voted reliably Republican.

Exurban and outer-suburban counties, many outside the reach of urban public transportation systems, make up 72 of the 94 most contested counties this year, according to a study by Virginia Tech's Metropolitan Institute.

Millions of voters have moved to new developments in sprawling exurbs over the past decade, trading longer commutes for larger or less expensive houses.

But many of those houses now stand empty, thanks to the foreclosure crisis and those that do find buyers sell for less than what they would have fetched a year ago.
