The best tool you have to do that is what the Democrat candidates are saying. I have no doubt most Conservatives will be scared into supporting McCain by the Democrats. Simply saying “Well their worse” isn’t going to work.
What I suggest is you simply post what the Democrats Candidates are saying on what ever issues the person angry at McCain is posting about.
If they are mad about taxes, post what Obama and Hillary plans are on taxes. Mad on immigration post their immigration plan.
The Democrats themselves are your best chance of changing peoples minds about McCain.
Frankly I personally think it is a waste of time. I think McCain’s record has so poisoned the well that you are wasting your time. However, if you are going to insist on spaming the board with McCainiac campaign ads, at least be an effective, rather then an obnoxious, campaigner.
SHOW ME WHERE I'VE SPAMMED THE BOARD WITH MCCAIN CAMPAIGN ADDS?
You do have severe mental issues! One time is a mistake but time after time when you keep babbling absurd accusations is just pure unadulterated brain damage. I've asked you again, and again, to SHOW ME WHERE I'VE DONE WHAT YOU'RE ACCUSING ME OF AND GUESS WHAT... ZERO/NADA/ZIP. Are you in some kind of fantasy world. Hello?! Is anyone there?! Please take your medication.
