The race for Nevada’s Electoral College votes remains close, but for the fourth time in the last five months John McCain has a slight advantage. The latest Rasmussen Reports telephone survey shows McCain attracting 45% of the vote while Obama earns 42%. This is the third straight month to find Obama’s support at the 42% level. Two months ago, McCain was at 45%, but his support slipped to 40% in July. When “leaners” are included in the current Nevada totals, McCain is on top 48% to 45%.
