Memorial Day Weekend is generally a benchmark for the start of the real Presidential cycle. With that in mind here are the three most recent polls I could find pitting McCain against Obama.
Gallup: McCain 47 – Obama 45
Rasmussen: McCain 46 – Obama 44
Newsweek: McCain 46 – Obama 46
Seeing as though recent polls have shown a generic Congressional Republican candidate running about 10-12% behind a generic Congressional Democrat candidate, the McCain campaign should be wild that he is drawing even with Obama at this stage in the race.
