"Hope and Change had a powerful appeal. But tonight I’d ask a simple question: If you felt that excitement when you voted for Barack Obama, shouldn’t you feel that way now that he’s President Obama? You know there’s something wrong with the kind of job he’s done as president when the best feeling you had was the day you voted for him.” - Mitt Romney, GOP Convention
So. You buy a new car (stay with me). You are so dang excited the day that you buy it, that you play your favorite song in it, and take any excuse to take it out for a drive. You drive around the block twice, just because you're not ready to say goodnight to the car. Even though it's not really dirty, after just two days, you wash it in your driveway, and take the time to dry it, and even buff it a little til it shines.
Four years, and 75,000 miles later, you don't take every excuse to drive around the block, and you don't wash it as often as you used to. That doesn't mean you regret buying the car. It just means that excitement wanes.. the "new car" feeling slowly fades. Even when you're pleased about something, you aren't always going to jump up and down.
I was at Barack Obama's acceptance speech, when he was declared President of the United States. And I cried and jumped up and down when his victory was announced. I was thrilled, and it was among the most memorable nights of my life. And while I haven't cried or jumped up and down for him or with him since that day, it doesn't mean that that there is "something wrong". My confidence in him (and in the vote that I gave him) hasn't changed. I just stopped jumping up and down. At least on the outside.
