No politician ever says they're going to be more liberal/more conservative in the face of an upcoming election. None of the Red State Dems from the 2014 cycle ever said "I'm going to be more conservative than usual", but everyone who looked at their voting record could tell what they were doing.
Expect Johnson/Kirk/Toomey to state their firm beliefs in conservative policies, while also throwing the occasional vote for moderate/liberal bills to brag about.
I think he is referring to more about the gun issue, and 2nd amendment rights than anything else, because he hasn't sponsored any bipartisan legislation. Toomey and Kirk has, but they contributed to the gridlock and fillibustering of bills outside the gun background check.
