Countering the Party of the rich stigma

A couple of years ago I was told that 90% of the billionaires in the country, and 75% of the fortune 500 CEO’s are either democrats or openly support the democrat candidates. I attempted to verify this by getting the names from Forbes. Getting the names was easy, but the party affiliation was much more difficult so I was not able to get as far as I would have liked. From my limited research, I did find that those statements appear to be true. Perhaps the Republican party should finish that research with their greater resources. If it proves to be true, as I believe it will, they can use this to counter the democrats. Whenever a democrat claims the republicans are the party of the rich, or that the democrats are the party of the poor / average folk, the republicans should run ads exposing the actual statistics.
