That's my point. Jeffords was a RINO and he jumped to benefit himself at a time when it would hurt us the most. I am advocating NOT electing them in the first place. Principled men and women in office would eliminate this worry.
Of course one of them could die. And it's very much the case that any one of them could be caught up in a scandal, but that is much more likely to be a Democrat.
I am dealing in reality. RINOs cannot be trusted. You seem unable to consider them as anything other than our friends, but hold the 'cross over' threat over our head in the same breath.
Spain has also proven unreliable... using your strategy we should install bin Laden as the next Prime Minister.
