Romney leads President Obama 47 percent to 45 percent in the latest Gallup tracking poll conducted during the four-day period following Romney's selection of Rep. Paul Ryan of Wisconsin as his vice presidential pick, and the 3-point margin of error means the race is essentially a dead heat.
"Mitt Romney's standing in the presidential election campaign has not changed materially in the immediate days after his announcement of Wisconsin Rep. Paul Ryan as his vice presidential running mate," the Princeton, N.J., polling firm said in a statement.
Romney was at 46 percent in the survey before he named Ryan Saturday.
But with the conservative enthusiasm after the announcement, Gallup suggested Romney might get a delayed bounce in the tracking poll. A USA Today/Gallup poll released Sunday found 39 percent of the 1,006 U.S. adults polled rated Romney's choice of Ryan as either "excellent" or "good," while 42 percent called the choice "only fair." Nineteen percent has no opinion.
The Gallup Daily tracking poll is a random sample of 1,863 registered voters 18 and older living in all 50 states and the District of Columbia. The survey has a margin of sampling error of plus or minus 3 percentage points.
