(Newser) – John McCain is leading Barack Obama by 48% to 45% in the latest Gallup poll, McCain's highest level of support since early May, Politico reports. Both candidates earned an expected convention bounce, but McCain’s boost was more immediate. Obama was ahead 49% to 43% among registered voters before the Republican convention last week.

Presidential nominees historically see a 5-to-6-point jump in Gallup’s polls following a convention, a factor that will likely affect polling through the middle of next week. Rasmussen's daily poll today tallied a tie between the two candidates, which wiped out Obama's 6-point convention bounce. CBS News had them tied half-way through last week's GOP convention.
