You just need to seek the file back to the start:

with open("blurbs.csv","rb") as f:
    blurbs = csv.DictReader(f, delimiter="\t")
    for row in blurbs:
        print row
    f.seek(0)
    for row in blurbs:
        print row

Alternatively you can wrap the dictionary generation into a list of dicts and operate on that:

with open("blurbs.csv","rb") as f:
    blurbs = list(csv.DictReader(f, delimiter="\t"))
for row in blurbs:
    print row
for row in blurbs:
    print row
