I frankly think a takeover of the House is a long shot. I do believe though that we can make some pretty major inroads and significantly weaken Pelosi.
It's going to take a force majeure to prevent a GOP takeover of the House. There has never been a case where any party is ahead by 7-10% in the Rasmussen generic congressional polls or ahead by over 2 points in the RCP generic congressional poll average, and that party has not ended winning the House. You can't be ahead by 10% and then somehow manage to lose in the districts.
It's like the presidential elections. If you are ahead in the overall polls by say 5%, it's virtually impossible for you to end up losing in the electoral college votes.
