Just as Republicans were preparing their talking points to tout a tightening of the so-called 'generic ballot' (a poll that aims to determine the electorates' general preference for party control), along comes a spider.

Over the weekend, the GOP was smiling about polls from Pew and ABC that showed a Democratic lead over the Republicans of only 4% and 6% respectively - But that picture has changed dramatically.

From Politicalwire:

• The latest Fox News poll gives Democrats an edge on the generic congressional ballot, where they lead Republicans, 49 percent to 36 percent. The survey also showed Democrats were more excited about the elections, and more motivated to vote, than their Republican counterparts. "More Democrats (37% ) than Republicans (26%) say they are extremely interested in tomorrow's elections, and more Democrats (89%) than Republicans (81%) say they plan to vote for their party's candidate in their district."

• CNN's final national poll before the elections shows President Bush's approval rating dipping to 35 percent and Democrats leading Republicans on the generic congressional ballot, 58 percent to 38 percent.

The average of these two polls gives Democrats a massive 16.5 point advantage over Republicans with just hours until the voting booths open.

VOTE!!!
