Has the Conservative Media bubble convinced its audience that GOP will win back power after the Midterms?

No, not in the least. What is PROBABLE is that the GOP will pick up a couple of seats in the Senate and a few seats in the House. In other words, the media, not just the conservative media, has shown indicators that the Democrats will not hold as many seats in Congress as they do at present. Not winning back power but making some modest gains. And that is the way it is.
