The Democrats promised change when they took the Congress over in 2006. From American Thinker’s Jared Harold (article ) here is some of the change you got:

Gasoline up from $2.19 to $3.35 or 53%
Unemployment up from 4.5% to 5% or 11.1%
National dept per ca pita was $27,677 then and now $31,551 or 14% higher.
Congressional pay increase.

Consumer confidence at multiple year lows.
Equity value of mutual funds down $2.3 trillion.
Home equity values down $1.2 trillion
Congress’s approval rating at all time low.

If you vote for change, you may want to be more specific.
