Whether you re-rush or not is your decision as others have said. Before you make a decision though you should ask yourself these questions:

1. Is there anything that stands out in my mind as something which might have prevented me from getting a bid?

2. If there is, what can I do to rectify this issue? In other words, what has changed now compared to then that might increase my chances?

Personally, I'd advise against it. I had the option to re-rush a group this semester that declined me last, and I didn't. Chances are if they don't want you once, they won't want you a second time.
