Take that republican convention.
In a CNN/Time/Opinion Research Corp. survey out Wednesday afternoon, 55 percent of Iowa registered voters who were questioned said that Obama, D-Illinois, is their choice for president, with 40 percent backing McCain, R-Arizona. That's more than double the lead Obama had in a University of Iowa poll taken early last month.
"Obama is winning in all regions of the state, even in the western counties, where George W. Bush beat John Kerry by 17 points," CNN Polling Director Keating Holland said. "Obama is winning rural voters in Iowa, not something you see in many other states."
It appears to be a similar story in Minnesota, where the Republicans are holding their national convention this week.
The poll indicates that Obama has a 12-point lead over McCain, 53 percent to 41 percent.
That's up slightly from a 10-point lead Obama held in a Humphrey Institute survey taken last month.
We only post polls when they're good ones.
