Talk radio is the reason Republican base voters have unrealistic expectations, Senate Majority Leader Mitch McConnell said on Tuesday, adding that it may have contributed to Donald Trump’s win in the party’s presidential primary.

“A lot of base voters have been really misled by a lot of talk show hosts and others about what’s achievable when you don’t have the White House,” McConnell said at an event sponsored by the American Enterprise Institute, responding to a question about why voters seem to be fed up and have largely favored outsider candidates over the course of this year’s presidential election.
