The presidential campaign of Sen. Ted Cruz, after giving up on Florida, rushing into Ohio before Trump did and campaigning hard in Illinois, goes all in to get as many delegates as possible in Illinois, Missouri, North Carolina and Ohio.

According to Politico, Ted Cruz’s campaign is pouring another half a million dollars into television and digital ad buys slated to run in Ohio, Illinois, Missouri and North Carolina ahead of the contests in those states on Tuesday:

“It’s all about acquiring delegates in an effort to defeat Donald Trump,” communications director Alice Stewart said of the ads. “We are identifying areas where we see a need to target our message.”

The influx of resources is yet another sign that the Cruz campaign sees opportunities to close the gap with Trump in Illinois, Missouri and North Carolina and win more delegate and that maybe there is a shot that Cruz could even win Ohio:

The investment in Ohio — expected to be Cruz’s biggest additional outlay — could indicate that his campaign sees an opportunity to land a stronger-than-expected finish in that winner-take-all state, where Trump and Ohio Gov. John Kasich currently hold strong leads. Cruz last campaigned there on Sunday night in Columbus.

Cruz remains within 90 delegates of Trump according to the Real Clear Politics Republican delegate tracker.

Donald Trump – 460

Ted Cruz – 370

Marco Rubio – 163

John Kasich – 63

There are 367 delegates up for grabs in the six Republican Primary contests to be held on Tuesday in Florida, Illinois, Missouri, North Carolina, Northern Marianas and Ohio.
