Ted Cruz has a new ad out titled “Supreme Trust” that goes after Donald Trump on potential SCOTUS picks, saying that “we’re just one Supreme Court justice away” from losing on “Life. Marriage. Religious liberty” and “the 2nd Amendment.” The ad also shows the clip of Trump telling Tim Russert that he’s “very pro-choice” and would not support a ban on partial-birth abortion.

Game on.
