This is the solo part, you can see how I play this at 2:24 in this video:

Capo on the 2nd fret:
e|-14-12-10-9-10----10----9-7-5-3-5/3------------|
B|---------------10----10-------------5-3--------|
G|-----------------------------------------------|
D|-----------------------------------------------|
A|-----------------------------------------------|
E|-----------------------------------------------|
[ Tab from: http://www.guitaretab.com/t/taylor-swift/336562.html ]
e|-14-12-10-9-10--------10-12----10-14----10-----|
B|---------------10--10-------10-------10--------|
G|-----------------------------------------------|
D|-----------------------------------------------|
A|-----------------------------------------------|
E|-----------------------------------------------|
If you want to play the intro like I did in the video, keep the capo on the 2nd fret and play:
G D A G D A
e|-0h2---|-0h2-|-0-------|-0h2---|---|---|
B|-----3-|-----|---2-2/3-|-----3-|---|-2-|
G|-------|-----|---------|-------|-2-|---|
D|-------|-0---|---------|-------|-0-|---|
A|-------|-----|-0-------|-------|---|-0-|
E|-3-----|-----|---------|-3-----|---|---|
Hope you like it!
