Hey Rick,
The Above quotes, that were said by Dan Quayle, are as follows:

"The vast majority of our imports come from outside the
country" J.Danforth Quayle

"If we don't succeed, we run the risk of failure." J.Danforth Quayle

"One word sums up probably the responsibility of any
Vice President, and that one word is 'to be prepared'."- J.Danforth Quayle

"I have made good judgments in the past. I have made good
judgments in the future."- J.Danforth Quayle

"The future will be better tomorrow."- J.Danforth Quayle

"I stand by all the misstatements that I've made."- J.Danforth Quayle

"A low voter turnout is an indication of fewer people
going to the polls."- J.Danforth Quayle

"We are ready for any unforeseen event that may or may
not occur."- J.Danforth Quayle

"It isn't pollution that's harming the environment. It's the impurities in our air and water that are doing it."- J.Danforth Quayle

"It's time for the human race to enter the solar system." J.Danforth Quayle

I am not sure of the origin, of the other quotes attributed to Kerry, in the original post, but considering the Inaccurate reporting of these, they are probably Bushisms. LOL
