Gallup reported today that Democrats have taken a 6-point lead in the polling firm's generic ballot testing, a striking change from its earlier polling. One shouldn't take too much from one poll, especially when it's not in line with most other polling, but Democrats sure hope it's the start of a trend.

"[I]f these numbers held through Election Day, the two parties would be nearly tied at the ballot box, with possibly a slight advantage for the Democrats," wrote Gallup's Lydia Saad, noting the poll was taken of adults, not likely voters, and that Republicans often have a 5-point turnout advantage.

The survey was conducted last week, which Gallup points out is when Democrats successfully passed a Wall Street reform bill that the party says will protect consumers and taxpayers from another financial meltdown.

"The financial reform bill is the second-biggest piece of legislation to get through Congress this year, after healthcare reform, and it enjoyed majority support" among American adults, Saad writes.

Interestingly, while Republican support on the generic ballot test fell from 46% to 43%, GOP enthusiasm spiked 11 points since last week. Of the Republicans polled, 51% said they were "very enthusiastic" about voting this year.

Where the GOP lagged was among independent voters, whose support for Republicans dropped 5 points to 43%. Democrats, who saw an incrase among all voters from 47% to 49%, in turn received a 5-point boost from independents, 39% of whom said they would support the Democratic candidate.

Rasmussen also released its weekly generic ballot test, which found Republican ahead by 9 points.
