In US, "having" the Senate has been mostly meaningless since filibuster became a standard feature of every vote. And without a filibuster-proof majority in the Senate you really can't do all that much regardless of the platform. Not only that, but the issues that are most prominent in the rhetoric tend to be the more polarizing ones (which should come as no surprise, since that's exactly the kind of stuff that rallies "your" voters to the polls), and thus are the least probable to actually push through by getting votes from a few defectors on the other side.
