Good speech.
He certainly needed to begin to repair his relationship with the rank and file conservative base.
And one key way to do it was to remind them of what the opposition intends to do should they win in November.
Hopefully that should provide enough clarity.
Best way for McCain to heal the breach with Conservatives is for him to go fight a big messy battle with Senate Democrats on spending or something to show he actually means what he says. He has time to do that while Hillary/Obama continue slugging it out.
Words are not enough. McCain’s record is against him. He needs to put up some solid deeds to match his rhetoric
