Reaching out across to the other side is fine and dandy - when the other side also happens to be on the right side, or when you think you can draw them to the right side (for up to and including the rhetorical bowl of soup). Screwing over the right side by giving the wrong side 50%+ of what they want is the wrong kind of bipartisanship. History is clear - when it comes to politics, "consensus" is a dirty word.
It’s usually a “reach around” rather than a “reach across”. Makes the Democrats feel good, but there’s no reciprocity.
