Millions of young Americans have graduated from college during the Obama presidency ready to use their gifts and get moving in life.

The future is not Big Government. Self-serving politicians. Powerful bureaucrats. This has been tried tested throughout history. The result has always been disaster. President Obama your agenda is not new. It's not change and it's not hope.

It's pretty cool to be able to hang out with the President and have the race-winning car on the South Lawn.

Al Gore the former vice-president of the United States lives in a mansion that uses more electricity than the average family's bungalow! David Suzuki rides on a bus that uses more fuel than a Smart car to get across Canada! Oh my God! And this is just the tip of the vanishing iceberg!

Campaign behavior for wives: Always be on time. Do as little talking as humanly possible. Lean back in the parade car so everybody can see the president.

My approach to cutting spending as president is to do a ten percent across the board cut of all federal agencies and then ask each of my new agency heads to find another ten percent by drilling down.
