One can support a party and then change to not supporting a party for a variety of reasons. Such as disagreeing with the direction the party is going, especially locally, or even as simple as eschewing the previously supported party because you are betting the other one will win and need to curry favor.

Sure, but why argue the abstract when we have Andreessen’s views and actions on record?

I haven't studied Andreessen's views and actions, so I was just positing a strategic reason for a change in political support for a high profile person. (as opposed to a drastic change in their thoughts which is what I take to mean as "radicalized")

For example, I have always preferred most of Democrats' positions on the national level, but on the local/state level, especially in California/Oregon/Washington, I disagree with a lot of the Democrat leaders, more and more since 2010 (I would say my views have not changed much, but the party's priorities at the state and local level have).

Of course, I'm nowhere near as influential as Andreessen nor do I have interests that would warrant a say in national politics, but I can see why if one is against local leadership, they would cozy up to someone who they think can help you fight against them, without being "radicalized", per the above definition.
