Palmer's United has a more centrist appeal than Trump does, from my understanding.
As for the topic, an election like 1990 might look like:
280: Barack Obama/Ron Wyden(Democratic/Labor) - 39.44%
(Bob Hawke/Paul Keating)*
213: Rob Portman/Elizabeth Dole(Republican/Liberal) - 35.04%
(Andrew Peacock/Peter Keith)**
45: Tom Golisano/Bill Walker(Independent & Reform/Australian Democrats) - 11.26%
(Michael Macklin/Norm Sanders)***
0: Doug Burgum/Walter Jones(Libertarian/Country) - 8.42%
(Charles Blunt/Bruce Lloyd)
Others - 5.85%
*Obama/Hawke=Incumbent Leader; Wyden/Keating=Former Treasurer/Senate Committee thereof
**Portman/Peacock=Former Commerce Minister/Trade Rep.; Dole/Keith=Labor Minister/Sec.
***Golisano/Macklin=From big province/state; Walker/Sanders=from isolated state/province
