I made that stat up but I believe the sentiment (“truthiness“?) holds.   Paul Waldman, The Keystone XL Issue May Be Resolved With—Shocker—Democratic Capitulation:

The current Democratic effort to help Mary Landrieu win her runoff election by scheduling a quick vote on the Keystone XL pipeline has to be one of the most politically idiotic moves in recent history. As I argued yesterday, not only is it guaranteed to fail in its goal of helping Landrieu, it gives Republicans a huge policy victory while getting nothing in return. Runoff elections have extremely low turnout, and the only way Landrieu stands a chance is if she can convince lots of Louisiana Democrats to go to the polls to save her. This kind of me-too policymaking—I’m just as pro-oil as Republicans are!—is about the last thing that’ll pump up Democratic enthusiasm.

Harry Truman called out me-too policymaking over 60 years ago:

I’ve seen it happen time after time. When the Democratic candidate allows himself to be put on the defensive and starts apologizing for the New Deal and the fair Deal, and says he really doesn’t believe in them, he is sure to lose. The people don’t want a phony Democrat. If it’s a choice between a genuine Republican, and a Republican in Democratic clothing, the people will choose the genuine article, every time; that is, they will take a Republican before they will a phony Democrat, and I don’t want any phony Democratic candidates in this campaign.

(Hat tip to Ron C for the Truman quote.)
