I was just wondering if Paul has any chance of winning at least 1 of these 3?

DC from 2008:

Maryland from 2008:

Wisconsin from 2008:

It looks like all 3 states are closed which means only Republicans can vote. But looking at DC close to 6000 people voted only. Can Paul pull at least 2500 to 3000 to pull a win here at least? And is it too late to still register as Republican for any of these three?
