Story highlights Wisconsin's largest newspaper is backing John Kasich for the GOP nominee

The paper said Ted Cruz and Donald Trump cannot govern

Washington (CNN) Wisconsin's largest newspaper is backing John Kasich for the GOP nomination, one week before the state holds its Republican primary.

The Milwaukee Journal Sentinel on Tuesday encouraged its readers to vote for Kasich next Tuesday, going so far as to call him "the only thoughtful candidate with a fundamental belief in long-standing democratic principles who remains standing in the GOP primary field."

Donald Trump and Ted Cruz are currently favored over Kasich in the Wisconsin Republican primary. Each is eager to claim momentum as the Republican election calendar slows to a crawl.

In endorsing Kasich the Journal Sentinel said Cruz and Trump cannot govern.

"Trump is Trump -- vacuous, unqualified and dangerously ignorant of foreign affairs," said the editorial board. "Cruz is brilliant but unable to escape the twin straitjackets of ideology and ambition."
