Should Celebrity Endorsements of Political Candidates Matter?

I could care less about which celebrity endorses who. What matters to me is the records of each candidate.
Of Obama:
1. Am I and those I know better off now than we were 4 years ago?
2. Has he kept All, Most, Some or None of the promises he made in 2008?
3. Has he proven himself to be not only a competent leader but also a competent commander-in-chief?
4. While campaigning, has he flip-flopped on any issues?

Of Romney:
1. How did Mass fare under his term as governor?
2. Has he kept All, Most, Some or None of the promises he has made?
3. While campaigning, has he flip-flopped on any issues?
4. What is his stance on national and foreign matters?

After I weighed these options, Obama lost out to Romney in my mind. These past four years have proven his undoing due to his policies, failure to keep promises, poor foreign relations skills, violations of US Constitutional law (for example, taking a foreign office in the UN while being president of the US), abysmal rate of recovery in comparison to past presidents who had similar economic situations, and how he has flip-flopped on issues, doing now what he said he wouldn't do back in 2008.

In the case of Romney: As governor, Romney presided over a series of spending cuts and increases in fees that eliminated an up to $1.5 billion deficit. He signed into law the Massachusetts health care reform legislation, which provided near-universal health insurance access via subsidies and state-level mandates and was the first of its kind in the nation. Job growth in Massachusetts rose , the annual rate of job growth was improving by his last year in office, moving Massachusetts up from last place nationally to 28th, as opposed to being 47th when he first took office in Mass. While I do not agree with Romney on issues like Gay Rights, what we need right now is economic stimulation and growth.
