A Republican senator who desperately needs Donald Trump’s endorsement for a runoff election later this month was ridiculed on social media Tuesday for his obvious attempt at appealing to the president’s massive ego.

Sen. John Cornyn (R-Texas) may be the incumbent, but his political career could be toast later this month if Texas Attorney General Ken Paxton beats him in a May 26 runoff election for the Republican nomination.

A recent poll of Republican voters had Paxton leading Cornyn 48% to 45%. So far, Trump hasn’t endorsed either candidate, despite promising to “make a decision … maybe relatively soon,” a few days ago.

Since time is obviously of the essence, Cornyn apparently decided to use his power as a senator to rename a highway after the president — perhaps in a bid to sway Trump to his side.

Cornyn’s legislation would designate U.S. Route 287, which runs through Montana, Wyoming, Colorado, Oklahoma and Texas, as a future interstate highway that would be renamed I-47 to honor Trump, the 47th president ― get it?
