There have been plenty of "Men, What Can Dems Do to Win Your Vote" discussions, both online and IRL, and they pretty much always go the same way (at least online, I can't know what's happening outside my circle IRL)
The answers given all either are about frustrations with either women or one minority group or another, OR they're complaining about wanting to see something from Democrats that they already do/are better about than Republicans. Examples of what I'm talking about include complaints about the economy, lack of job creation, and "doing nothing for the Average American" when ALL numbers show Dems are better for the economy and job creation, and the only reason Dem presidencies haven't accomplished more is because of Republican obstruction.
So...what else is there they can do?
