How can you debate a lefty when you can't speak the truth about them without it being labelled a personal attack?
Opponent: "Candidate X voted to raise taxes 28 times."
X: "That's a scurrilous personal attack."
Opponent: "X is quoted right here as saying he thinks the military is wrong and should be disbanded."
X: "Another right-wing attack dog charge. Americans are tired of negative campaigning"...
The party of no ideas.
All they can do is be negative.
