A new poll is giving the lead to Senator Barack Obama in Washoe County -- a key battleground within the swing state of Nevada.

Suffolk University's poll found support for Obama in Washoe at 45 percent, and support for McCain at 41 percent.

One week to go before the election, Suffolk also gave the lead in Nevada to Obama.  The poll found 50 percent support for the Illinois senator, 40 percent for Arizona's senator.  Suffolk also says 94 percent of Nevadans participating in the poll have made up their minds about who they plan to vote for.  Only one percent said they were undecided and five percent said they may change their minds before voting.

The poll was conducted the 23rd through the 27th.  Suffolk says the study of 450 had a margin of error of plus or minus 4.6 percent, and 95 percent level of confidence.
