|Sen. Michael Bennet and Hillary Clinton|
Due to the Republican Party’s struggles in Colorado, Politico has just lowered Bennet’s vulnerability to 9th from their previous 7th.
Politico only kept Colorado in its top ten list due to the expected competitive nature of the presidential race and because no other senate race appears more competitive (note Politico ranks Arizona 12th).
