Top Indiana Democrats trashed Mike Pence on Tuesday as a gaffe-prone politician who “doesn’t think very deeply about his convictions” hours before the Republican governor was set to take the stage for the first and only vice presidential debate.

“One thing that those of us in Indiana know about Mike Pence is that he is capable of a gaffe that follows doubling down on an extreme position,” said Indiana House Democratic Leader Scott Pelath during a press call hosted by the Democratic National Committee.
