I gave up on him a while ago.
For me it was the trifecta immediately after 911 when he did nothing about the border, went to a mosque to praise Islam as a "religion of peace," while the smoke was still billowing from the New York rubble, then started talking about Iraq and the "Iraqi people" constantly.
I don't care at all for his deceptive newspeak about the borders and our sovereignty, "work Americans won't do," I'm against amnesty," his contemptible line about "vigilantes," referring to American citizens, etc.
To me, it's difficult to listen to this, know what he is up to and trust him on anything else.
