I think as a whole, talk radio helps the Democrats
24/7 nonstop attacks against the left. Demonization..... Commies, Fascists, Liberals hate America, They want to take our guns, They want gays to be like you and me, we are the "Real Americans", God likes us best
The biggest impact of talk radio is not that it has destroyed the Liberal movement, but it has destroyed the moderate Republican movement. It forces Republicans to assume extremist positions and provides Democrats with an unending supply of talking points and a means to fear monger
Talk radio alienates moderate America and forces them to support moderate left positions because there are no moderate right positions
And Democrats help right wing talk radio.
Clinton made Rush Limbaugh.
Ratings go sky high when Democrats are in office.
