Why even bother with actual audio of Democrats and liberals and protesters when you could preface it as "they say one thing but liberals are liars. This is what they really mean: [insert manufactured audioclip]"
The right already does that in practice now. Mark Levin's spin on the family separation was that Democrats say they care but they really don't, they only really care about power and were using the children as political pawns. Imagine if they could make audio to have Democrats say what they always insist Democrats really mean.
