I would amend one of the comments about the dems moving further left when the opposition moves right to read.......

while the left continues to veer harder left and when the oppsoition moves right at all.....the dems start calling names, sending accusations, posing more government controls and employment all the while calling for more effort in the left direction.

Visualize a semi truck driver (dem) pulling steering wheel full left turn.
Now visualize a steering wheel on the passenger side, not connected to anything, with the driver (opposition) trying to turn right!!!
