I managed to win the Presidency once with Bachmann, but it was only after winning Iowa and getting the endorsements of the other conservatives left in the race. So it doesn't really count. On my own though, I managed to win quite a few primaries with Bachmann in a different game (only people like Johnson and Hunstman and Santorum had dropped out). I'm pretty pleased with myself.
Perry kept getting momentum shifts. Meanwhile, I got virtually nothing off double wins in New Hampshire and Iowa (I guess because the results were so close). I mostly barnstormed on leadership, War on Terror, and Military Intervention (I think... I did this some time ago... I just remember I used the only "+1s" for Bachmann in Iowa and NH). I'd tried in other games to win Iowa and South Carolina, but I was finding that whatever little momentum I'd get in Iowa would be long gone by the time SC came around. My strategy for Iowa and New Hampshire basically relied on winning debates and getting last-minute endorsements.
