Polling by Rasmussen on the generic choice for Congress, which has been a Democrat leaning poll for as long as its been done, untill the last few months. Reps overtook Dems back in March and have held pretty steady. Lest anyone think the poll is gamed, go look at last November and see how his polling showed a result similar to the actual election. Gallup, I think, still has a Dem advantage but the Republican number has risen from 20% to about 26-27%; more importantly, the Democrat number has declined and independents have risen and the indie's are leaning against the Obama/Dem agenda form bailouts to cap-and-trade to government health plan.
