I didn't know this about McCain.
He will NEVER get my vote.
However, even though he is leading in the presidential nomination, John McCain has not yet succeeded in convincing the primary wing of the Republican Party - the conservatives - that he is the right candidate. One of the reasons is that he often spoke and voted against the majority Republicans, as in 1999 when he asked for more intensive air bombing of Serbia.
In April of that year, three weeks after the bombing commenced, he announced that the US is in danger of losing the war to the Serbian Army which has "antiquated machinery" and "absolutely no military air power", if massive strategic air attacks are not initiated. "Attacks on any infrastructure target must not be prevented. We all regret civilian losses, as well as our own, but they cannot be avoided," he said.
