Politics: need a little help here

I got a letter in the mail today from my local APWU, American Postal Workers Union, who I know supports Obama (they sent a letter previous stating such).

The letter was about John McCain, specifically "what do we know about him?"

First there's this, "McCain's record does not match up to his image as an independent thinker". It says he supported Bush's position 95 percent of the time in 2007, supports Bush's tax cuts for the wealthy and supported the failed plan to privatize social security. In my opinion this doesn't make him an independent thinker but a Bush supporter who will continue the current process of war in Iraq and letting the country go down the tubes.

Next is "McCain said he doesn't really understand the economy and the he doesn't believe we're headed into a recession". That doesn't make sense, it appears to me our economy is in big trouble no end in sight either. An interesting thing I read today about how the price of oil has gone from $25 a barrel to $108 with no end in sight and yet Bush says "nothing to worry about" and it would seem McCain would agree with him.

Then, "McCain also has a very troublesome record on trade and outsourcing". It says he voted for NAFTA, CAFTA and to allow China into the WTO dspite evidence that the U.S. has lost more than 1 million jobs because of NAFTA and 1.8 million jobs since China entered the WTO. He also supports tax breaks for companies that ship jobs overseas and voted to weaken Buy American laws that keep jobs at home. It would seem to me that right there's a reason for a weakened economy, no way to keep people employed if the jobs are going over seas.

Lastly there's this, "McCains proposal will jeopardize our health care". They don't give any specifics just some statements. "McCain's plan undermines existing employer based health care and pushes workers into the private market to fight big insurance companies on their own. It will reduce benefits, increase costs and leave many with no health care at all. I don't know much about his health care policy so I'm in the dark on this but it doesn't sound very good.

So like I said at the beginning, they are for Obama and against McCain but is any of this true?
