McCain cannot win if all he has going for him is that he is not Obama. The democRats will turn out and vote and the Republicans will stay home.
McCain is strong on Iraq, on the War on Terror, he wants to make us energy independent the sensible way, by proposing drilling and nuclear, the only real viable options, he said he will nominated judges like Roberts and Alito, he wants to make tax cuts permanent, he is for securing the border, he is firmly pro-life. What more do Republicans want?!
And the bottom line is still McCain or Obama — pick one.
