Yup, Lugar was pretty good back in the day. I actually favored him among the “Seven Dwarves” of the year 2000 Republican presidential primary because he proposed to abolish the income tax and replace it with a national sales tax (The IRS is the root of all evil IMHO).
But then he went down hill fast. Same thing happened to Barry Goldwater as he aged. Time is not kind to the brain or any other organ for that matter.
How did he vote in the impeachment trial of Clinton?
