To the Editor:I would like to respond to Mr. Clifford Knudson’s assertion that he has always loved Tennessee because the state, until recently, was a “blue state.” Mr. Knudson obviously is one of those who likes to throw around facts before checking his sources.In the last 10 presidential elections, Tennesseans have voted Republican eight times, the exceptions being 1992 and 1996. I have to assume Tennesseans simply voted for their favorite son (Al Gore) those two years.
