Douglas Holtz-Eakin said the only similarity between McCain's economic plan and Bush's is a commitment to keep taxes low.

``Sadly, it seems that is all President Bush understood in the economy,'' Holtz-Eakin said in an interview to be broadcast this weekend on Bloomberg Television's ``Conversations with Judy Woodruff.'' It is Barack Obama's budget plan, not Senator McCain's, that resembles Bush's policies, he said.

``It's dedicated to the recent Bush tradition of spending money on everything,'' Holtz-Eakin said.
