Democratic presidential candidate Hillary Clinton is heading to Michigan next week, just two days after Republican presidential candidate Donald Trump delivers an economic speech to the Detroit Economic Club.

According to sources familiar with her visit, who weren't authorized to speak for the campaign, Clinton will do a big-ticket fundraiser in Birmingham and another, more public event in southeast Michigan on Wednesday, although details have not been worked out yet. The Clinton campaign would not confirm that she is headed to the state.

With the political party conventions wrapped up and the general election season well underway, the presidential tickets are focusing on a few key swing states, including Ohio, Pennsylvania, Colorado, Florida, Virginia and now Michigan.

Republican vice presidential candidate Mike Pence, the governor of Indiana, was in Grand Rapids and Novi last week. Democratic vice presidential candidate Tim Kaine will be in Grand Rapids to help open a campaign office on Friday, and Trump is scheduled to speak to the Detroit Economic Club at the Renaissance Center on Monday.

Michigan has been a reliably blue state since 1992 when voters have chosen the Democratic candidate for president by mostly wide margins. A poll conducted for the Detroit News and WDIV last weekend after the Democratic convention wrapped up showed Clinton with a nine-point lead over Trump in Michigan.

Donald Trump headed to Detroit for Economic Club speech

In 2012, Republican presidential candidate Mitt Romney, a native son of Michigan, didn't campaign in the state after the party's convention in Tampa. In 2008, Sen. John McCain pulled his campaign out of the state in September after it became apparent that Michigan wasn't in play.

But Trump hopes to capitalize on working class voters, who have been hurt by trade deals and a subsequent decline in manufacturing jobs.
