Democrats Top Roll Call's Endangered Incumbent List

With Montana Democrat Sen. John Walsh dropping out, Democrats Mark Pryor and Mary Landrieu appear to be battling out to top Roll Call’s most endangered incumbent list.

Sen. Mark Pryor, D-Ark., is still in a perilous political position, but Louisiana Sen. Mary L. Landrieu has leapfrogged him on the list to become the Senate’s most vulnerable incumbent.

The Democrat is pushing hard to eclipse 50 percent on Nov. 4, the day of Louisiana’s jungle primary and possibly Landrieu’s best opportunity for re-election. She will undoubtedly get close. But if Landrieu doesn’t win a majority of the vote against a few GOP challengers, she will likely face Rep. Bill Cassidy, R-La., in the Dec. 6 runoff.

If that happens, all bets are off, and Landrieu’s viability may depend on which party prevailed on Election Day.

After Landrieu and Pryor, the third, fourth and fifth spots go to Mark Begich, D-Alaska, Kay Hagan, D-N.C. and Mark Udall, D-Colo. respectively.

The only Republican on the list is GOP Minority Leader, Kentucky’s Mitch McConnell.

Slots 7 through 10 are all Democrats, as well. They are, in order, Mark Warner, D-Va, Jeanne Shaheen, D-N.H., Jeff Merkley, D-Ore and Al Franken, D-Minn.
