Now that the two party conventions are over, it appears that the debate over which candidate would receive the bigger bounce has been settled.

John McCain's announcement of surprise-pick Sarah Palin largely stepped on Barack Obama's post-convention coverage, and Palin's stellar address -- and public unveiling -- last Wednesday, helped generate an enthusiasm for the ticket among Republicans and solidify a positive convention for the GOP.

Early indications suggest that Palin power has turned the race upside down. McCain has leaped to the lead in a new USA Today/Gallup national poll. A brand new CNN/Opinion Research Center poll released moments ago, confirmed the USA Today/Gallup results. Among registered voters, Obama and McCain were knotted at 48 percent.

The survey shows McCain at 50 percent and Obama at 46 percent among registered voters -- the first time since an early January USA Today/Gallup survey that the Republican was at the critical 50 percent mark.

Among those most likely to vote the gap was even broader with McCain leading Obama 54 percent to 44 percent.
