Well, in that case, the Democrats should adopt policies that attract more left leaning voters. Saying stuff like, "I will prosecute migrants" doesn't make any sense because if that is an important topic to a voter, why wouldn't they just vote Trump who has promised that and more?

If the problem is, "not enough left leaning votes", the solution seems like, "attract more left leaning votes". People in this country love progressive leftist policies like universal healthcare or not funding genocides, no matter their party affiliation. People have not responded well to neo-liberal/conservative policies like means testing school lunches or increasingly stringent border laws.

And yet, the Democratic party continually adopts neo-liberal/conservative policies. It feels like voting Democrat is just, "voting Republican but slower". The Democratic party has accepted the Republican framing about an imaginary migrant crisis, and that was with a much more firm stance against racism only 4 years ago. Yeah, they would possibly be better on Israel's genocide than Republicans, but all the actions protesting the genocide have been met with vitriol from the current administration. It seems far more likely that the Democrats would just do the same thing as Republicans, just less loudly.

The Democratic party cannot expect to win simply because, "orange man bad". They have not shown they will not continue to adopt Republican ideas and policies. If they want people to vote for them, they should do things to attract those voters. They should stop doing things that pushes away voters.
