It would be interesting to find the raw gaps in votes in double-barrel Senate seats.
Last election Minnesota saw at least 150,000 voters split their votes between Klobuchar and Housley.
The gap for governor was only 50k, so a double-barrel Senate race in Georgia would actually be a real opportunity for Dems.
Since 2008 (there was none between 1996 and 2008):
OK 2014 had no significant vote splitting.
SC 2014 (the D candidate against Lindsey Graham overpolled the other by 20000 votes).
NY 2010 (probably roughly 103000 voted voted Schumer and DioGuardi)
MS 2008 (80000 split votes between Cochrane and Musgrove).
WY 2008 (probably 6000 electors voted Enzi and Carter)
