You're not alone peg y don, I struggled with quite a few on this.
You mentioned 18d, I haven't solved that either. Anyone know the answer?
Also stumped by:
1d. Passing over Republican 3 (6) D...t.
In case it helps, the answer to 3 is 'want'.
4d. Way to accommodate batting practice (7).
r...i.e
24d. Circle huge last letter (5).
