Sen. Ted Cruz speaks about net neutrality at Capital Factory in Austin, Texas, Nov. 14, 2014.

The percentage of conversation about Sen. Ted Cruz that was positive on Facebook fell after the Texas Republican criticized net neutrality, calling it "Obamacare for the Internet."

Positive interactions related to Cruz on Facebook dropped from 52 percent over the period of Oct. 29 to Nov. 4 to 34 percent from Nov. 5 to Nov. 11, following the firebrand Texas senator's reaction to Obama's embrace of net neutrality, according to data supplied by Facebook.

The percentage of negative interactions for the first week examined was 44 percent, with 4 percent of the interactions being neutral. For the later time period, the percentage of negative interactions was 61 percent, with 5 percent of the interactions being neutral.

Facebook - which supplied the data about the interactions to ABC News as part of a partnership - defines interactions as "posts, comments, likes and shares" on the social network.

On Monday, a message shared on Cruz's Faceboook page read, in part, the "biggest regulatory threat to the Internet is 'net neutrality.' In short, net neutrality is Obamacare for the Internet."

A large spike of conversation related to Cruz - a possible 2016 contender for president - occurred from Nov. 10 through Nov. 12. The positive interactions for the senator on those dates was just 26 percent.

The president released a video Monday explaining why he was in support of net neutrality.
