Well, no.

That assumes that offspring follow their parents' ideology directly. While many may, some will not.

What we've seen over time is a defection from e.g. religious right upbringing, especially as offspring move into denser urban areas.

Yes there’s departures, revivals, and reversions to the mean.

But two parents who feel strongly about something having children will produce children with a certain biological proclivity.

It’s a lot to bet that people will deny their own biology.

There isn't a biological proclivity to liberalism!

Yes, but aren't there biological proclivities to certain personality traits, and then proclivities of people to certain personality traits to political ideology?

So if liberals don't reproduce, it could start selection against the "openness to experience" personality trait.

A small, anecdotal example of this... there is a family in my community that is part of the conservative christian organization called "Quiverfull" that believes in having very large families. The one in our community has 12 children. They see it as creating members for their religion but I would be surprised if more than a couple of these kids end up following along (based on who the kids are turning out to be).
