What Kennedy did was bring Americans together. The mistake most politicians are making today is to try and handle the world's problems in a hope to make a name for themself. I believe a better plan would be to elect a leader that places their focus on our country and the world can follow by our example.

Currently the only candidate that fits that description is -

Duncan Hunter = Vietnam Vet 173rd Airborne & 75th Army Rangers
His son = USMC 2 terms in Iraq (& not behind a desk)
Also committed to bringing industry back to US

If we are to continue being a great country we can't dependent on the rest of the world to be our industrial base... My 2 cents...
