2010   14508.2   8.92   a

why is D loves to make (+)plus signs to (-)minus signs, while R loves to make (-)minus to (+)plus ?
specially George W. Bush (R) (January 20, 2001 - January 20, 2009) , he can makes -1.24 to 10.01

I'm at lost here... the D & R makes the opposite actions.
I don't know witch is good for a country who holds international currency  
I'm not good at economy, any thoughts ?
