I don't think a mortgage banker who has been a member of the Knights of Columbus for over 30 years and switched from Democrat to Republican in the past decade (a time in which many socially liberal Republicans became Democrats and socially conservative Democrats became Republicans) fits the profile of a "celebrity politician."
I don't know enough about Jim Matthews to make a judgment about him, but I think being endorsed by a conservative such as Lynn Swann says more about his character than the fact that his brother happens to be Chris Matthews. (Chris Matthews, BTW, used to be a conservative Democrat but has become more liberal as time has gone by.)
I posted this story in part to see if FReepers can shed some light on Jim Matthews's views and record; hopefully we'll know a bit more about him in the coming days.
Well it's always possible that Jim Matthews is a conservative, I mean, look at Ron Reagan (the pantywaist son, not the Gipper) vs. his Dad...politics doesn't always run in the family.
