u.s. of 'a'?

I have to weep, not for the future, but for the present.  Why?  Because I heard this on the radio today:

'Did you know that California is the only state in the U.S. that ends with the letter 'a'?'   

Yeah, this is from a professional radio show, granted, they are a bunch of douchers, but still they get paid for this show.  In case you are missing any of them, the states are:

• Alaska
• California
• North Carolina
• South Carolina
• South Dakota
• North Dakota
• Montana
• Virginia
• West Virginia
• Alabama
• Arizona
• Oklahoma
• Indiana
• Iowa
• Louisiana
• Minnesota
• Florida
  
• Nevada
• Nebraska
• Georgia
  
• Pennsylvania

That is just over twenty states, two out of every five states.  Four states away from being half of the country.  How do people not at least think of some of these state?  

Were they educated in Kansas?
