Good things suggested so far... 700c or 27" wheels are fine if you are super concious of where you ride. But with roads like that, not paying attention and dropping into huge potholes will destroy standard 700c wheels pretty quick. If you go with a 700c wheel, get some stellar rims like the Sun Ringle CR-18 and be very concious of where you direct your wheels.

A 26" wheel, on the other hand, will generally be much stronger. Smaller diameter wheels will hold up better, and 26" bikes take bigger tires, so there is a lot more rubber and air pressure to protect the wheel. Schwalbe Marathons or Big Apples are awesome tires that hold up well, roll pretty quick, and have good flat protection.

If you don't want to worry about it, go with a 26", either a rigid mtb, hybrid, or similar. If you want more speed, go with a 700 with beefy rims just avoid the big bumps.
