Senator Coons won’t be much different than Senator Castle. Mike Castle had a 28 ACU rating in 2008. He is slightly better than the “Dingbat Twins” from Maine, but not by much.
If I recall correctly, Castle has a lifetime ACU rating in the 50s. Not great, but nothing like all the liberals with single digit ratings.
There is a big difference between Castle and Coons ... if Castle wins, it's a step toward the GOP regaining control of the Senate. If Coons wins, it's a step away from that.
It's not just how a person votes. It's also whether he brings us back to the GOP control that will be essential to derailing the Obamanation agenda.
