What Lies the McCain campaign is telling and what you should know about them:
LIE: McCain claims that Obama wants to raise taxes for everyone, and that these tax hikes will cost American Jobs.
FACT: Obama wants to lower taxes for poor and middle-class Americans while getting rid of Bush's tax breaks for the wealthiest Americans (top 1%). McCain will Continue the Bush tax breaks, giving the biggest tax breaks to the wealthiest, and very meager tax breaks to the poor. The Washington post made a nice visual chart for you:

As you can see, people who make less than $100,000 a year, will in fact receive a bigger tax break from Obama than from McCain.
Obama also wants to give tax breaks to corporations who do NOT ship jobs overseas, and withhold those tax breaks from those who DO ship jobs overseas, in order to keep more Jobs in the US. McCain's policy of giving tax breaks to the rich won't accomplish that.
"Also keep in mind when thinking about taxation and spending, that John McCain supports making the tax breaks for the
wealthiest Americans permanent, and did not lift a finger when tax breaks for the lowest-income American were allowed to quietly expire. McCain also supports the policy of "borrow and spend" that took us from a national surplus (under a Democratic president, I might add) to a national debt of $9,692,762,945,925.31 (as of 09/09/2008). We're on track to be over TEN TRILLION dollars in debt (much of it to China) before Spring. Fiscal conservatives my ass! Don't believe me? Check out

LIE: "John McCain claims that Barack Obama wants to put the government in charge of everyone's health care and have bureaucrats make your health care decisions."
FACT: "Barack Obama said that if you already have health care, "keep it." and that if you can't afford health insurance, the government will help subsidize it so that you can afford it. That he wanted to give every American the chance to have the same health insurance and care options that members of congress now have." --- "If we apply McCain's logic on health care, we have to assume that Congress is in a terrible situation as far as their health care goes, because government bureaucrats, instead of medical professionals, make their health care decisions" (

Is Obama's plan perfect? No, but McCains health care plan will do nothing to provide health care for the over 47 million people in the USA that have no health care. No country has a perfect health care system, but very few first world countries have one that is as abysmally poor as the current US system. Fear Mongering about universal health care is just stupid, what do we really have to fear from everyone having health care? Having a Fiance that's a doctor and living in a country, where EVERYONE has health care, I like to think I have a bit of insight into this. My biggest insight: My fiance says he would never feel comfortable working as a doctor in the US because of the terrible health care system. He much prefers working here, where he earns less money, but doesn't have to deny patients care because they don't have insurance. Will Obama's plan cost money? Yes, but he plans to offset the cost with his tax plan (see above). The current government is spending $16 billion (yes that's BILLION!) a MONTH (every month!!!) on the Iraq war. I'm pretty sure the cost of a universal health care plan would be tiny fraction of the cost of what's going into our pointless war.
The lies the McCain camp has been telling continue on and on, they are just ridiculous. Yes, I stole large parts of this post from here:
http://www.robhamm.com/mylife/node/ . That's because I'm not an eloquent writer, and other people can say things far better than I can. I encourage everyone to go there and read the whole post however, it's well written and informative, and contains a lot more information.
