When I see someone say that the Democratic Party and the Republican Party are the same, I recall the bumper sticker that says something like "the Democratic Party isn't perfect, but those other guys are insane. The signs of their insanity(or is it mendacity?) are all around us. They're working hard to turn the clock back on women's rights, gay rights, and people of color. They've worked to gut the voting rights act and make voting as difficult as they can for people of color.
While it's still legal to get an abortion in this country, they've made it extremely difficult to do so. They're working hard to make contraception unattainable for many women. What kind of madman makes that difficult in a world bursting at the seams? Republican madmen. They've framed equal rights under the law for LGBT people as some sort of assault on their religious freedom. Christians are the vast majority in this country and somehow they're the victims? I don't think so.
Their avowed purpose has always been to do away with Social Security and Medicare, Medicaid, and Social Security disability, leaving the elderly and the disabled in the same situation they were in pre-Social Security--freezing to death or dying of hunger.
So, while I realize that most politicians are out of touch with their constituents and too much in thrall to corporations, I still see a significant difference between the two parties. Not as great a difference as I might wish, but a difference.
Those other guys? They're nuts.
