Abe, honestly

• “He’s striking a similar pose to Abraham Lincoln….”

The phrase is similar to. Whenever possible, keep a phrase together:

• “He’s striking a pose similar to Abraham Lincoln….”

This smooths out the sentence.

To be even more precise and, I think, elegant:

• “He’s striking a pose similar to Abraham Lincoln’s….”

Next we can debate whether he was really striking  the pose (consciously going for the photo op) or merely adopting  the pose, or perhaps just caught in a pose.

And then we talk about the politics of the moment. And then we can have a huge fight.

Or, we can just remember to preserve the phrase similar to, and leave it at that. Yeah, probably a better idea.
