We were sequenced behind a B-737 doing a visual to Runway 33L. As they landed Tower cleared another B-737 to line up and wait on 33L and; once the arrival exited the runway; the Tower cleared the holding B-737 for takeoff. They almost immediately aborted the takeoff and said they would clear at Tango. Tower told a taxiing aircraft to hold short of Tango so the B-737 could clear. Although there was sufficient room to do so they stopped before clearing the hold short line.I asked if we were still cleared to land and Tower advised the B-737 to move forward and clear the runway. They began moving and I felt they would be clear before we touched down so I continued. As we were in the landing flare we passed behind the B-737 and were rocked by a huge blast of jet wash. The aircraft was momentarily pushed sideways but I took action to recover and regained centerline alignment. The landing roll-out was routine and we cleared the runway.I radioed the Tower to inform them that we had encountered a lot of jet wash in the flare. Even though the B-737 was moving I was surprised by how much turbulence we encountered. I suspect that they gunned it right then for some reason even though they were moving or they were single engine. I should have elected to go around when I thought to inquire if we were still cleared to land regardless what the other flight was doing. An aircraft so close to our intended touchdown point should have been a clue for the possibility of jet wash. Just wasn't expecting that much.
As the reporter's A320 was on short final a B-737 cleared to depart the same runway prior to their landing rejected their takeoff but failed to clear the runway completely. When asked to expedite clearing the resultant jet blast struck the A320 as they flared causing momentary destabilization from which the reporter recovered and landed safely.
