The strategy that avoids the entire system being dismantled. Imagine if there were five congressional representatives from a new Social Democracy Party. Because those five representatives are the deciding vote if it goes along party lines, they can apply pressure on the Democrats to pass healthcare reform. Hooray, everyone loves the Social Democracy Party.

They might take a few more seats from the Democrats' safe districts in the next election. But in a contentious district where the Republican candidate has a good chance of winning, if half the people who voted Democrat vote Social instead, the vote gets split and the Republican gets in. So many of those people, who want to vote Social, will realize that if they do, then healthcare gets completely gutted. So they hold their nose and vote for the Democrat.
