The popularity of abortion rights
Somehow, a number of folks have got the idea that the Democratic Party's support (such as it is) for abortion rights is costing them votes. They think the Democratic Party must "compromise" (read: sell out) on abortion in order to compete.
This hypothesis doesn't seem to have any basis in fact. A state-by-state poll on abortion rights shows that there are only 15 states in which the majority supports the criminalization of abortion.
Among the states with majorities or pluralities supporting legalized abortion: Kansas, North Carolina, South Carolina, Georgia, Texas, Montana, Ohio, Iowa, Arizona, New Mexico, Virginia, Wyoming, Alaska, Florida, Colorado, Nevada, plus the usual suspects (California, Vermont, etc.).
Yet the perpetually politically brain-dead leaders of the Democratic Party seem think they'll improve their fortunes by playing Republican-lite on this issue.
