Trump is #TeamDino because Rossi is #TeamDonald.
Republican Dino Rossi went to bat for Donald Trump when it mattered -- at the 2016 Republican National Convention. Rossi was a Trump delegate who quashed attempts by other Republicans to nominate another candidate.
And Donald Trump has repaid Rossi by donating to his campaign. Trump desperately wants Dino Rossi to be elected because he knows that Rossi will be a rubber stamp for his anti-worker, anti-woman, anti-immigrant agenda.
And Trump is right.
Rossi is entirely beholden to the president, refusing to criticize the administration's policies, even as they threaten the livelihoods of farmers in his district.
