I'm not too familiar with E12s (I have an E15) but generically the kind of 
behaviour you describe could be the result of either severe friction in 
the 
drivetrain (dragging brake?) or insufficient motor field strength.  

If you have one of the E12s fitted with a PM motor, the later is obviously 
not caused by low field voltage, but it could be laid to field magnets 
severely weakened by overheating.

To understand the Republican party (or the Democratic party, 
for that matter), it is most efficient to look directly at the clients - 
or as political scientist Thomas Ferguson would call them, the 
"major investors." On that level, the ideological contradictions are 
unimportant. Political parties do function as mediating institutions,
only not for voters.
