In Boston where the headquarters of Republican presidential nominee Mitt Romney's national campaign are located, there were surprising few signs on Monday pointing to the fast approaching U.S. Presidential Election Day the next day.

Neither signboards nor banners were seen on the bustling streets and lanes in the capital and largest city of the Massachusetts state, one of the oldest in the country with a population of some 617,000.

One small signboard near the gigantic City Hall building reminded voters to cast votes on Tuesday in both English and Chinese, as Chinatown is not far away.

People here went about their businesses as usual, and in public places like restaurants, the upcoming polls were seldom talked about.

Even polling stations, which are usually located in schools and other public places, were not visible in the city. At one station inside a public library in Boylston Street, nobody was in sight.

Although Romney served as Massachusetts governor from 2003 to 2007, the state favors Barack Obama, the incumbent Democratic president seeking a second term.

Romeny and his foe were focusing again on swing states like Wisconsin, Florida, Ohio, Virginia and New Hampshire on the final day before the vote, as they are crucial for them to clinch the 270 electoral votes needed to win the White House.

A final survey of the campaign by CNN and the Opinion Research Center showed the race as a dead heat on Monday, with Obama and Romney tied at 49 percent.

The former governor and his wife Ann will cast their votes at 1335 GMT at the Beech Street Center in Boston's Belmont, where they live, his campaign announced Monday.

Though there was no obvious boosted security on Monday, Boston police will secure hundreds of polling stations on the Election Day with at least one officer posted at each location under the law.

Other measures will include road closures, parking bans and traffic diversions.

Boston police are also working with the Secret Service and state police to secure Romney's election night rally at the Boston Convention and Exhibition Center.

Citing limited space, the Romney campaign has denied foreign media access to its rally, while the Obama campaign allows almost all registered reporters to cover its rally in Chicago, the president's hometown.

A media relations officer from the Foreign Press Center in New York said the center had utilized all its resources both in Boston and Washington D.C. to cope with the "unprecedented" complication.

"However, it appears that the Romney campaign cannot make arrangements for foreign media," she said in an email.
