I don't think the constant throwing around of the word "lies" is helpful here at all, and I agree with some of you more sensible ladies that there are plenty of websites that support one view and plenty that support the exact opposite. I fear that most of the responses you will receive here are going to be designed to swing your vote to the candidate of the responder's choice rather than actually answer your question.
Politifact is one possible website but they've made some mistakes as well. Factcheck.org is another one that is accurate. Anything from the CBO (Congressional Budget Office) is completely non-partisan and involves a ton of number-checking. Neither the Republicans nor the Democrats have ever accused the CBO of being wrong - they just choose whether to cite the numbers or not.
Now, it's essential to sort out the rhetoric. For example, Romney/Ryan keep citing the $716 billion (I think that's the number they've been using) that "Obama took away from Medicare to pay for Obamacare." And that's the same number that Paul Ryan included in his own budget, so he must not have a problem with it really.
So both sides agree on the number, but conveniently leave out that not one dime of that came from senior citizens' benefits! It came from overpaid insurance companies and over-charging hospitals (and other providers). Also some waste & fraud - which I'm sure we all agree can be cut.
So you can argue whether or not that's a good idea, but you can't accuse Obama of taking that money away from seniors. Someone else posted $555 billion - but again, that is NOT taking money out of benefits! So read the fine print, folks!
The second thing is to evaluate voucher plans - if you are given a certain amount of money (as a credit) to buy your own plan (which is what Romney/Ryan propose), the questions to ask are: What guarantee do I have that I will, with costs rising and inflation, be able to actually purchase a plan with that money? If costs go up (which they will) and my voucher amount is fixed, how will I buy coverage? Am I guaranteed coverage regardless of pre-existing conditions? (Depends) If I have not been covered continuously and try to buy a plan, will I be covered for pre-existing conditions? (no).
What happens is that healthy people with few costs can buy their own private insurance, because the insurers love them. They will be able to use their voucher and, if they are well off, pay more out of pocket to buy an excellent plan. They pay premiums and don't require much in paid benefits. So the insurance companies make more profits. Some say "that's free enterprise" but others say "Isn't health coverage a fundamental right?" The sicker people without a lot of extra cash will be the only ones left on Medicare, and that will bankrupt the system a lot sooner. It's not affordable for the US and the system will implode much sooner.
And Romney's recently-stated plan that poor people can just to the ER if they are sick is very irresponsible. In fact, he worked to implement universal health care here in Massachusetts just to get away from that philosophy of "use the Emergency Room for a hangnail" that has driven costs up so absurdly over the years. It's financial unacceptable, and he knows it, and he said so himself when he was governor. I don't want my elderly mother in the ER with a doctor who doesn't know her and who's trying to care for her in an acute situation. I want her getting preventive care and avoiding the expense and the mental trauma of the ER. And I think everyone should have that fundamental right regardless of their economic or health situation.
