It makes sense to me that religious righties would support the Republican party because it is the only party that will promise to take away the rights of others to do things christianists believe their god would want stopped. Limitation of freedom based on religious values is their truth, and it's not new to our time period. They are on a holy crusade to ban all abortions including that of a girl who was raped by her father. Don't let logic ever get in the way of religious zeal.
And it is about forcing their values onto others as nobody in this country forces someone to get an abortion. No one forces them to choose to end their own lives if they are terminally ill (there are NO death panels except maybe in insurance companies). The right wants to block other people from marrying because nobody is going to force them to marry someone of their own sex. Most fundamentalists favor the Republican party or the tea party because it makes sense. I get that.
What doesn't make sense to me are the so-called economic righties. They vote based on something that isn't true at all. The Republican party is as big at spending as the Democratic. Oh they talk a good talk, but ask them what they will cut and it's usually waste... innocuous thing to say with no meaning but it suits those who kid themselves about what the Republicans are really up to-- which is shafting the middle class while increasing the power of the rich.
They are all for privatizing Social Security so that workers can invest their own tax money and not pay for grandpa already on Social Security. Ask people in the stock market how that works. Guarantees are non-existent unless the government guarantees the funds... and if it does, the only thing this will change will be Wall Street getting more of the pie.
I could go on and on about this but the following link says it better. If you read it, think about it, you may not be thrilled with the left but stop to think who it actually is who has been helping the shipping of jobs overseas, limiting wages, eliminating environmental controls on water and air for the benefit of corporations, making it easier for the rich to control ads and the airwaves, and finally a tax code that benefits the wealthy and is slowly eating away at the middle.
Admittedly the Democrats have not done enough about this. But do you honestly believe the Republicans mean to do anything. Oh they talk about liberating you to make your own fortune by ending all regulations on corporations or financial institutions. If you believe that is what that means, you also believe in Santa Claus. Good luck with that!
