Certain things stick in your mind about debates over the long term, usually blunders like George Bush checking his watch or Gerard Ford seeming to not realize that Eastern Europe was under Soviet control. Or one liners like "There you go again" and "Where's the beef."
But given a couple more weeks, most people are going to be hard-pressed to remember much about Tuesday's debate. No major mistakes were made and no memorable one-liners were delivered.
Remember the complaining mere weeks ago about how many GOP debates there were before the convention? Nobody remembers there were about 20 of them in the 2012 cycle, and hardly anyone can recall a single detail from then.
