If conservatives fail to defend America against the socialist party, they will help to deliver a mandate to President Obama. We all know who and what McCain is. And we know who and what the DEMs are. There's nothing to earn. The choice is clear. It's either McCain or Obama. You either help one or you help the other.
McCain doesn't own the votes of those he has repeatedly betrayed. McCain can earn them or spurn them.
McCain gets two choices come November. Principles or defeat. Betraying the first guarantees the second.
