I think the midterms will at least put a dent to it. A number of Dems are going to pay dearly for this mistake of a law. Obama is looking more and more like a lame duck by the day. 2016 will simply seal the deal.
Hillary doesnt need any accomplishments for 2016. Just having a D after her name guarantees victory. Heres how many electoral votes she starts out with as absolute locks:
California - 55
Connecticut - 7
Delaware - 3
District of Columbia - 3
Hawaii - 4
Illinois - 20
Maine - 4
Maryland - 10
Massachusetts - 11
Michigan - 16
Minnesota - 10
New Jersey - 14
New York - 29
Oregon - 7
Rhode Island - 4
Vermont - 3
Washington - 12
This totals 212 votes. You need 270 to win. This list does not include states that lean heavily blue like PA (20), NV (6), CO (9), and VA (13.) They total 48 votes. So Hillary starts out with about 260 electoral votes. And I am not including Iowa that has gone Dem seven out of the last 8 presidential elections or WI (10 votes), which has gone Dem the last 7 elections.
Any Rep is going to have an uphill battle to win. Hillary and any other Dem will be the favorites. FL or Ohio or WI will win for the Dems.
