I can predict that the exit polls on November 7 will show a Democrat landslide but when the actual votes are counted at the end of the day, Republicans will prevail and maintain control of the House and the Senate.
Why do I say this? Easy.
Exit polls are taken during the day - when most Republicans are at work driving our great American economy. Most Democrats don't work or work in government jobs which allow them to vote during the day. Exit polls reflect this heavy sampling of Democrats who vote during the day while the rest of us are working and earning a living for ourselves.
After Republicans get off of work, pick up their kids from school, do dinner, they finally get to vote.
This is why Exit Polls are usually so wrong.
