On one hand, the Democrats have a history of managing the economy correctly with moderate fiscal responsibility, maintaining social services, and pushing back on corporate excesses and warmongering. The last time we had a balanced budget was Clinton's.
On the other hand, Republicans claim they are better for the economy, although they are the ones that constantly crash it, do the most to worsen the debt and deficits, and take away living standards for the average American.
So who's better for the economy? It's so hard to tell.
The problem is that most voters are too uneducated to understand messages like this anyway, due to the aforementioned education crisis.
