As I said on this subject earlier, if you have to choose between 90% agreement (Rubio), 40% (Crist), or 10% (Dem) it makes since to go with the 90%, especially since 100% agreement is impossible for all of us, since we don’t agree with each other 100%.
The problem isn’t 40-90% agreement ... it’s what is the 10-60% disagreement?
When you can’t be certain about how a RINO is going to vote - you might just as well have a Dimo in the seat. You can be absolutely certain how they will vote.
