Democrats are hoping to pick up 20 or more seats currently held by retiring Republicans in the House. If they do, it will give them a lopsided majority in the next Congress.
Democrats currently have a 235-to-199 advantage in the House, and a 270-seat veto-proof majority is still wishful thinking. But they're eying a substantial number of the GOP's 29 so-called open seats.
The more they win, the easier it'll be to push through an agenda that includes raising taxes on the wealthy and cutting them for the middle class, while also expanding health care coverage.
Democrats also only have to defend one open seat for every five the GOP has to worry about. Of those, only two are considered competitive, and Democrats have a sizable financial advantage backing them up.
