I share your disappointment. The Democrats have backed down so much in the last 20 years that they're currently Eisenhower Republicans. It's dispiriting, and it's hard to be enthusiastic about most of these candidates.
Please vote. Here's why.
They're not all the same, and there is at least one huge difference between the parties.
If you are a woman, or have women in your family, or if you just like women, please vote for the Democratic party candidate. The Republican Party has almost uniformly opposed women's reproductive rights. Their record on equal pay is just as bad. The Democratic Party defends women's rights. Which do you want in control of Congress and the governors' offices?
Despite the depressing similarity of candidates and parties, the rights of half the people are at risk from one side. And no matter how competent or centrist the Republican candidates appear, control of the Senate and House will have the same result for women.
Please hold your nose and vote a straight Democratic ticket tomorrow. It's important.
