Presidents generally do what they are good at in their first four years, then spend their second term responding to the agendas imposed upon them by events.

The Hispanic population grew by 4.7 percent last year, while blacks expanded by 1.5 percent and whites by a paltry 0.3 percent. Hispanics cast 6 percent of the vote in 1990 and 12 percent in 2000. If their numbers expand at the current pace, they will be up to 18 percent in 2010 and 24 percent in 2020. With one-third of Hispanics voting Republican, they are the jump ball in American politics. As this vote goes, so goes the future.

Americans will gladly support their president when he attacks nations that sponsor or harbor terrorists. We will even back him in a preemptive war against a country that might attack us. But when we start sending troops around the world to stabilize nations that, if left to disintegrate, might become breeding grounds for terror, it's a step too far for most Americans.

Rebut the negative, and the opposing campaign has not merely lost a skirmish, it has suffered almost irreparable damage. An effective rebuttal makes it hard for the campaign whose ad is destroyed to be believed about anything ever again.
