Yes this is an alternative. But doing so can provide you with exactly the thing you do not want, someone marked "D" or "R".
Most that would not have such a label can not afford to run.
Someone that does not deserve such a label could go the party route to get elected, meaning Steelish is correct. They have to be examined.
I believe the number is 40% of the people are voting party regardless of who it is. So that means to be successful one needs virtually all of the "undecided".
