For the GOP, How BIG is B-I-G?

From every indication.
From every poll.
Via every seasoned judgment and every intuition.
According to every analytical measurement and every hunch and notion.
From all sides -- It sure as hell looks like it's gonna be BIG.
But how big?
Well, Jim Geraghty at National Review is looking at figures from The Hill and here's what he says:
Wow. The Senate races may still look tough for the GOP, but this year’s wave is hitting the House races, hard. The Hill 2010 Midterm Election poll, surveying nearly 17,000 likely voters in 42 toss-up districts over four weeks, points to a massive Republican wave that, barring an extraordinary turnaround, will deliver crushing nationwide defeats for President Obama’s party. The data suggest a GOP pickup that could easily top 50 seats (the party needs 39 for control of the House).
And here it is from The Hill itself:
Republicans are headed for a blowout election win that seems certain to seize more than enough seats to knock out the Democrats and take control of the House. 
Yes, a lot of people will be playing the expectation game over the next five or six days.
But I've seen too many elections to know better than to start assuming victory (let alone measuring the size of the victory) before every vote is counted.
