Running Against the 'Obama Economy' - And Winning?

I can't get my head around this:

In the weeks leading up to the midterm elections we have had the following economic news:

♦ Unemployment is at 5.9 percent, the lowest level since before the 2008 economic collapse.

♦ The Federal deficit dropped sharply in fiscal 2014, to the lowest percent of GDP since 2007.

♦ The consumer confidence index is at its highest level since 2007.

♦ Gasoline prices have dropped dramatically, falling below $3.00 a gallon for the first time in years.

♦ On the Friday, the stock market closed at a record high more than double what it was when Obama took office.

Yet Republican candidates are campaigning against the "Obama Economy". . . and many of them are likely to win.

Just how disconnected from the real world are the voters?
