DETROIT-- Hillary Clinton is ready for the Democratic primary to be over, and she made that very clear to supporters in Detroit a day ahead of the state's primary.

"The sooner I can become your nominee, the more I can begin to turn my attention to the Republicans," Clinton said, before launching into a riff against the "bluster and bigotry" in the opposing party.

Clinton probably didn't have to say it in order for that to be clear: She has increasingly focused her attention on a general election match-up against Republicans, especially their front-runner, businessman Donald Trump.

But Clinton is in an awkward position. Her campaign has emphasized that delegate math will quickly make it impossible fo Sanders to ever become the Democratic nominee. Her nearly 200 delegate lead is only expected to expand as more states vote.

At the same time, they have insisted that there is still plenty of primaries left, and that Clinton hasn't taken her eye off the ball. Sanders's campaign has also insisted that it isn't over yet.

Already, however, cracks are beginning to show. One of Sanders's top aides on Monday floated the idea of a Clinton-Sanders ticket -- with Sanders as the vice presidential half.

“Maybe they’re going to put him on the ticket then,” Sanders adviser Tad Devine told Politico's Glenn Thrush.

And so, on Monday night -- like clockwork -- Sanders was asked that very question during a Fox News town hall in Detroit. Would he consider it?

"We are talking about running this campaign to win to become president of the United States," Sanders said, dismissively. "I‘m not talking about vice president."

Asked less than a half hour later at the same forum, whether she would consider Sanders, Clinton chuckled.

"Let’s not get ahead of ourselves," Clinton said. "I don’t want to think any further ahead than tomorrow and the Michigan primary. I can’t do that."

That turned out to be not-quite true. At her campaign event just a few hours later, Clinton made it very clear that her eyes are trained on the Republican field -- and Trump.

"I mean you’ve got to say this about him: he’s an equal opportunity attacker," Clinton said of Trump. "He’s just gone after everybody."

"We will not let a person like that ever become president of the United States," she added as the crowd roared.
