No, he's really not. He's "both sides are terrible, no one wants to work anymore, and everyone's too sensitive" center right curmudgeon.

2016:

"There's been just too much funny business on both sides of the aisle."

"I think both individuals and both parties backing the individuals have a certain degree of insanity." Eastwood said in the same interview, "I'm not on either side of the aisle. I think most Americans are going, 'What the...? Is this all we can do?' ...When there were 17 people on the stage [in the early GOP debates], I thought, well, there are three or four people up there I could see voting for. They seem pretty good. I had a few...and then I thought, what the hell happened?"

In a red carpet interview with Extra on September 8, 2016, when asked about supposedly supporting Trump, Eastwood replied, "You know, I haven't supported anybody, really," and jokingly suggested that Trump and Clinton constituted a modern-day Abbott and Costello, referring to the bumbling comedians of the 1940s and early 1950s.

Then he endorsed Michael Bloomberg in 2020. That's it.
