Hi, I understand what it means but I don't know about what it "holds back"? Hope my question is clear Emotion: thinking

"In Washington right now, we don’t see the kind of leadership that would give us faith,”
Obama continued. “It’s the timidity, the smallness of our
politics that are holding us back.”

'The timidity and smallness are holding us back (= impeding us) from...' but you have not provided enough of the context to show us what Obama is talking about trying to accomplish.

Hi Mister yes there isn't enough context after "holding us back" it's written a new phrase "Another voice from out of the darkness: “You’re looking pretty good!”
Maybe before it? "In Washington right now, we don’t see the kind of
leadership that would give us faith,” Obama continued. “It’s
the timidity, the smallness of our politics that are holding us
back.”
Maybe, but I have already read that and told you that I think it is in the greater context.
