(CNN) I feel like a unicorn these days, because I did not oppose Brett Kavanaugh's nomination to the Supreme Court at first, but I do oppose it now. Why? Entirely because of the character issues raised about him.

Countless times, I heard some fellow Republicans say they found both Dr. Ford and Brett Kavanaugh believable during last Thursday's hearings, and then come up with explanations that strain credulity to avoid taking her side. Maybe she was confused about who the boy was, they offered. They said the burden of proof was on her and since they were both equally credible, she hadn't met it. Give me a damn break. This is like when you get asked at a banquet if you want chicken or fish. It's one or the other, not both.

I do not oppose Kavanaugh now because he is more conservative than I am, particularly on social issues. Elections have consequences. A President gets to pick Supreme Court nominees who reflect ideology important to the President's party. Whether I like it or not -- and unless you've been under a rock for two years, you know I don't like it -- Donald Trump is President. Anyone he picks will come from a list of conservative jurists approved by the Federalist Society. All will be in the same ideological mold of Neil Gorsuch and Brett Kavanaugh. Justice Gorsuch shares a similar legal and educational background to Kavanaugh's, but was easily (though narrowly) confirmed. There is one important difference: Gorsuch did not get accused of sexual assault.

The ideology of a nominee, and factors like race, gender, ethnicity and creed, are all solely the President's choice. But there are other requirements for a Supreme Court appointment that should not be optional. A Supreme Court Justice should have intellectual heft, judicial temperament and lifelong fitness of character.

There is no doubt Kavanaugh meets the intellect requirement. And until two weeks ago, I also thought he had judicial temperament and fitness of character. He has gone through six FBI investigations and served on the federal bench for 12 years. People I know worked with Kavanaugh in the past and describe him as a "Mr. Rogers" type of guy. In his first hearings, he came across as calm and deliberative -- a cross between a Boy Scout and an altar boy.
