I haven't heard a coherent argument for supporting McCain yet. The only argument I hear is: "He's electable." Ah, McCain had 69% of Maricopa County (Phoenix Arizona) Republicans vote against him. Is the GOP going to make the same mistake as the Dem's in '04, by going for the "electable" candidate. Say hello to President John Kerry. Kerry was so "electable" that he couldn't even run again this year, due to his "botched joke" about our soldiers in Iraq.
“I haven’t heard a coherent argument for supporting McCain yet.”
That’s because there isn’t any, as you say “Coherent” argument for his support. Zip, Zero, Nada, unless of course the voter is Democrat.
