Let's not be naive. Your feelings about who is the leader of the party does affect the other candidates.
Some years ago I listened to a radio interview with a Republican who had lost in a primary to the Republican nominee for Senator. That Republican nominee in turn was far, far behind in the polls at the time, (and eventually did lose big), to the Democratic candidate Joe Lieberman.
Speaking of his own party's candidate, the Republican admitted that a victory was unlikely, but said that money still needed to be spent on the campaign.
"We have to get his numbers up, even if he loses", the Republican said. "With these numbers, he'll drag down everyone else on the ticket", he added.
It is not possible to entirely disconnect your feelings about one party's leader and his policies from your feelings about all candidates from that party. That is simply basic practical politics.

You might be sure, but at the moment things seem to be shifting.
