The senate races in 2014 do not, initially, look that good for Democrats. First, there are are more Democrats than Republicans running (20 seats are now D and only 14 are now R). Second, many of those 13 are in strongly Republican states, while some of the 20 are in states that are not that strongly Democratic.
It doesn't look good.
But look closer. Here are the 13 Republicans who are (or at least might be) running for re-election (the 14th is now held by DeMint, who will be replaced by another Republican soon):
Jeff Sessions (AL)
Jim Risch (ID)
Saxby Chambliss (GA)
Pat Roberts (KS)
Mitch McConnell (KY)
Susan Collins (ME)
Thad Cochran (MS)
Mike Johanss (NE)
Jim Inhofe (OK
Lindsey Graham (SC)
Lamar Alexander (TN)
John Cornyn (TX)
Mike Enzi (WY)
12 of the 13 voted to protect rapists
12 of the 13 voted against a UN treaty on rights of the disabled
All 13 voted against middle class tax relief
8 of 13 voted against extension of payroll tax holiday and unemployment insurance
9 of 13 voted against FDA food safety modernization
