Cruz just returned to the Senate:
"It is a division Mr. Cruz helped create, by pressing congressional Republicans to defy party leaders and their colleagues to shut down the government and repeatedly hold up basic legislation, giving him the distinction of being the least popular member of one of the world’s most exclusive clubs.
But outside the noise and theatrics of the campaign, Mr. Cruz also finds himself at a potential turning point in his Senate career, both as a returning failed presidential candidate and as an unpopular firebrand who has been most comfortable as a thorn, rather than partner, to other Republicans"

He has many fences to mend before he can even tread water with his contemporaries. However, stranger things have happened.
