Do the Democrats have any all stars now?

I was thinking about this. During the recent Democratic administrations, Obama and Biden, there were always Republicans who acted as thorns in the side of the Dems; people like Rubio or Cruz. People who Republicans supporters latched onto as people who fought against the administration.

In the Trump administration, who is that for the Dems? I can't really think of any Dems who would be nationally known and acts as a choice of opposition. All the Dems I can think of are as old as dirt, or no one really seems to care about them.

Who are the heros for the Dems that are standing up to the Trump administration?
