No, Weylon, because changing the tense also changes both the entire structure of the sentence and its meaning. In this context, the word "had" is an auxillary verb, or a helping verb. When it is used, its purpose is to modify the verb that follows it, so that following verb must be in the past tense. It shows a condition that might have occurred or taken place if another action had also taken place, and the entire structure is dependent upon the word "if".
1. Would you have voted for Bigly if he had ran for president?
2. Would you have voted for Bigly if he ran for president?
3. Would you vote for Bigly if he ran for president?
Sentence number 2 makes no sense whatsoever due to the word "have", because the word "ran" in this instance means subjunctively. The tense doesn't match.
