Fence-sitters just means unbiased observers.
Looking at Republicans, their tax cuts exploded the Deficit and Debt. Totally irresponsible.
Looking at democrats, they spend wayyyyyyy too much on everything. Totally irresponsible.
Both parties suck.
The 70's and 80's were kinda ok for debt. But if you sit back and watch the scrabbling crowd defend their party, what the opposite party did was so bad, their own party didn't reverse it. So for example, if the tax reduction was so bad in the last administration, has this administration reversed it? So it doesn't matter who's in, they're as bad as each other, they're just in for the money.
